Buffer bots: The role of virtual service agents in mitigating negative effects when service fails
Authors: Sands Sean , Campbell Colin , Plangger Kirk , Pitt Leyland 
Published: September 2022

AbstractIn recent years, marketers have placed increased reliance upon artificial intelligence (AI) and, subsequently, the use of virtual agents in customer service contexts is on the rise. Despite such service digitalization, service can still fail. While there is an increasing literature on the effect of virtual agents in service settings, questions remain as to how customers react to service failure that results from interactions with virtual service agents. To this end, we deconstruct the effect of virtual agent service failure across two studies: one involving a process service failure and another involving an outcome service failure. We specifically manipulate the type of service agent that causes the service failure (human vs. virtual agent) and the magnitude of the failure (small vs. large). Results show that firms can leverage virtual service agents to mitigate or buffer the negative effects of service failure. From a managerial perspective, our findings suggest that firms could engage virtual service agents in situations where there may be a risk of outcome service failure—particularly in settings where relatively large magnitude failures may be experienced. In such a setting, we find that virtual service agents can mitigate the negative effects of service failure, more so than when the failure results from an interaction with a human service agent.
Digital presence in service recovery: The interactive effect of customer salutations and employee photographs in email signatures

Published: September 2022

AbstractService firms can manage failure apology emails depending on how much digital presence or lack thereof they wish to maintain toward aggrieved customers. While nascent research indicates positive effects of higher levels of digital presence, the efficacy of this strategy in service recovery settings remains unclear. Drawing on the concept of digital presence and the unified theory of social relations, the authors investigate the potential detrimental effects of combining certain salutation forms with digital presence in the form of employee photographs in these emails. The data were gathered using one survey among service employees (Prestudy, N = 202), and two scenario‐based experiments (Study 1,N = 418; Study 2,N = 449). Study 1 assesses customer reactions to different apology emails and shows that personalized salutations (i.e., addressing customers by first name) and digital presence in the form of employee photographs can negatively interact to affect recovery satisfaction and repatronage intentions, with customers' perceived rapport mediating these relationships. Moreover, the results of a second experiment (Study 2) show that compensation after a service failure can mitigate the negative interactive effects. This study thus suggests using digital presence (in the form of employee photographs) in conversations with aggrieved customers only when customer salutation personalization is absent.

ScopeMilk fat globule membrane (MFGM) is an essential component of milk. Bovine MFGM (bMFGM) has been shown to support cognitive development and increase relative concentrations of serum phospholipids. This study investigates bioavailability of bMFGM components after oral administration in two preclinical models to explore whether dietary bMFGM induces parallel changes to plasma and brain lipidomes.Methods and resultsTransgenic APOE*3.Leiden mice (n = 18 per group) and Sprague–Dawley rats (n = 12 per group) are fed bMFGM‐enriched (MFGM+) or Control diet, followed by phospholipid profile‐determination in plasma, hippocampus, and prefrontal cortex tissue by targeted mass spectrometry. Multivariate analysis of lipidomic profiles demonstrates a separation between MFGM+ and Control plasma across rodents. In plasma, sphingomyelins contributed the most to the separation of lipid patterns among both models, where three sphingomyelins (d18:1/14:0, d18:1/23:0, d18:1/23:1[9Z]) are consistently higher in the circulation of MFGM+ groups. A similar trend is observed in rat prefrontal cortex, although no significant separation of the brain lipidome is demonstrated.ConclusionbMFGM‐enriched diet alters plasma phospholipid composition in rodents, predominantly increasing sphingomyelin levels in the systemic circulation with similar, but non‐significant, trends in central brain regions. These changes may contribute to the beneficial effects of bMFGM on neurodevelopment during early life.

Published: September 2022

AbstractIntroductionNocturnal enuresis (NE) is a common pathology in children that can have significant behavioral, emotional, and social impacts on a child's life. Recent studies have assessed PTENS as a potential treatment method for NE, particularly in those who do not respond to initial first‐line treatments. Literature has shown varying results with regard to its success. There has been no systematic review and meta‐analysis to date assessing outcomes following this treatment.ObjectivesDespite multiple studies showing the potential benefits of PTENS in NE, there has been no consensus regarding its efficacy. The aim of this study was to systematically analyze the effects of PTENS on children with NE.Study DesignIn September 2021, a search of PubMed, Embase and the Cochrane Library was carried out for studies relating to outcomes following PTENS in children with NE. Studies included were original publication English language randomized controlled trial (RCT's) with at least ten children receiving parasacral transcutaneous electrical nerve stimulation (PTENS). After assessing for relevant studies, data were collated and analyzed from the included studies. Risk of bias was assessed using the Cochrane seven domain assessment. Our primary outcome was response and nonresponse to treatment. These results were combined in a fixed effects meta‐analysis model to obtain an overall estimate of the success rate. Information regarding demographics was also collected. There was no external funding for this review.ResultsOf 145 studies found initially, four RCT's (208 children) were included. The weighted mean rate of full response to active PTENS was 10.8% (0%−19%). All studies considered, meta‐analysis showed no difference between PTENS and controls (RR: 0.70, 95% confidence interval [CI: 0.37−1.32]). Subgroup analysis of monosymptomatic enuresis showed no effect of PTENS compared to controls (RR = 0.58, 95% CI: [0.24−1.42]). When grouped, studies comparing PTENS to sham/behavioral treatment showed no benefit compared to controls (RR = 0.81, 95% CI: [0.05−12.53]) and those comparing PTENS to biofeedback/interferential current (IFC) showed no difference to controls (RR = 0.69, 95% CI: [0.36−1.33]). There was no evidence of a difference between cases and controls between these latter subgroups (RR = 0.70, 95% CI: [0.37−1.32]).Discussion/ConclusionOur results suggest that PTENS has no clear benefit in the management of children with NE compared to controls. Subgroup analysis showed that its use in monosymptomatic NE has no clear advantage. However, this review has highlighted the need for further high quality studies. Limitations to this review included a relatively small sample size and the use of prior or concomitant therapies.

How we approach complex vascular anomalies and overgrowth syndromes
Authors: Watson Katherine D. , Kim Kyung R. , Blatt Julie 
Published: September 2022

AbstractVascular anomalies, both vascular tumors and vascular malformations, can occur in isolation or as part of syndromes including those which feature phenotypic overgrowth. To update what is known about vascular anomalies associated with overgrowth, PubMed was searched for “overgrowth syndromes and vascular anomalies or malformations.” PubMed, OMIM, and the Rare Disease Database also were searched for specific diagnoses. We review individual overgrowth syndromes, provide a case‐based approach to the clinical, radiographic, pathologic, and genetic basis for diagnosis, to complications of both the vascular anomalies and the overgrowth, and emphasize the need for a multidisciplinary approach to care.
Large‐scale top‐down proteomics of the Arabidopsis thaliana leaf and chloroplast proteomes

Published: September 2022

AbstractWe present a large‐scale top‐down proteomics (TDP) study of plant leaf and chloroplast proteins, achieving the identification of over 4700 unique proteoforms. Using capillary zone electrophoresis coupled with tandem mass spectrometry analysis of offline size‐exclusion chromatography fractions, we identify 3198 proteoforms for total leaf and 1836 proteoforms for chloroplast, with 1024 and 363 proteoforms having post‐translational modifications, respectively. The electrophoretic mobility prediction of capillary zone electrophoresis allowed us to validate post‐translational modifications that impact the charge state such as acetylation and phosphorylation. Identified modifications included Trp (di)oxidation events on six chloroplast proteins that may represent novel targets of singlet oxygen sensing. Furthermore, our TDP data provides direct experimental evidence of the N‐ and C‐terminal residues of numerous mature proteoforms from chloroplast, mitochondria, endoplasmic reticulum, and other sub‐cellular localizations. With this information, we suggest true transit peptide cleavage sites and correct sub‐cellular localization signal predictions. This large‐scale analysis illustrates the power of top‐down proteoform identification of post‐translational modifications and intact sequences that can benefit our understanding of both the structure and function of hundreds of plant proteins.

AbstractIntroductionPulmonary agenesis is a complete absence of the pulmonary parenchyma, airways, and vasculature unilaterally or bilaterally. Although bilateral cases are lethal, the outcome of unilateral cases remains not well described. We performed a comprehensive literature review to assess the clinical features of pulmonary agenesis.MethodsFour database sources were searched on October 10, 2021 and two cases were included from our institution. Studies related to the clinical impact of comorbidity and intervention on the survival outcome in pulmonary agenesis were included for full‐text review.ResultsWe identified 259 patients—with right‐sided (59%), left‐sided (34%), and bilateral agenesis (7%)—among 195 articles and our two cases. Additional anomalies included cardiovascular (40%), skeletal (30%), gastrointestinal (20%), tracheal (20%: all stenoses), and genitourinary (14%) anomalies. Fifty‐seven (24%) individuals in unilateral pulmonary agenesis had isolated disease. Outcomes related to survival were not uniformly reported, but the 2‐year overall survival rate of unilateral agenesis was 62% and no subsequent death was reported until 13 years of age. The right‐sided agenesis was more frequently associated with tracheal stenosis (27% vs. 11%, p = 0.003) than the left‐sided disease. A multivariable analysis indicated that tracheal stenosis (hazard ratio [HR]: 2.2, 95% confidence interval [CI]: 1.3–4.1, p = 0.003) and gastrointestinal anomalies (HR: 2.0, 95% CI: 1.1–3.3, p = 0.010) were prognostic factors for mortality.ConclusionsThe poor prognostic factors were tracheal stenosis, right agenesis, and gastrointestinal anomalies. Treatment for these comorbidities is a key point for improving the survival of unilateral pulmonary agenesis.

Published: September 2022

AbstractIn this paper we study the application of four‐mode squeezed states in the cosmological context, studying two weakly coupled scalar fields in the planar patch of the de Sitter space. We construct the four‐mode squeezed state formalism and connect this concept with the Hamiltonian of the two coupled inverted harmonic oscillators having a time‐dependent effective frequency in the planar patch of the de Sitter space. Further, the corresponding evolution operator for the quantum Euclidean vacuum state has been constructed, which captures its dynamics. Using the Heisenberg picture coupled differential equations describing the time evolution for all squeezing parameters (amplitude, phase and angle) have been obtained, for the weakly coupled two scalar field model. With the help of these evolutions for the coupled system, we simulate the dynamics of the squeezing parameters in terms of conformal time. From our analysis, we observe interesting dynamics, which helps us to explore various underlying physical implications of the weakly coupled two scalar field system in the planar patch of the de Sitter cosmological background.
Characterization of motion power loss of off‐road wheeled robot in a slippery terrain
Authors: Shafaei Seyed Mojtaba , Mousazadeh Hossein 
Published: September 2022

AbstractFor the first time in realm of power study of off‐road wheeled robots, this study deals with motion power loss due to slippage of robot wheels traversed on slippery terrain. For this purpose, effects of slippery terrain type (solid balls with diameter of 0.0127, 0.0254, and 0.0508 m), tire air pressure (20.68, 34.47, and 55.16 kPa), and robot forward speed (0.17, 0.33, and 0.5 m/s) on the power loss were characterized. Derived results proved that the increasing effect of slippery terrain type on the power loss was dominant (1.08 and 3.21 times) than that of robot forward speed and tire air pressure, respectively. Meanwhile, the increasing effect of robot forward speed on the power loss was prevailed (2.98 times) than that of tire air pressure. Hence, to minimize the power loss of the robot traversed on each type of slippery terrain, adjustment of robot forward speed should be considered as first priority. A comparison between motion power loss (43.60–249.40 W) and provided motion power for the robot (136–436.37 W) implies that 12.93–75.44% of provided motion power was wasted by slippage of the robot wheels on slippery terrains. Overall, the analytical results obtained in this study lead to open a new prospection for comprehending of the power loss trends of off‐road wheeled robots traversed on slippery terrains. As slippery terrain composed of solid balls, the results can be especially utilized for final phase of unloading robotic operations of catalyst handling procedure in process towers and reactors of oil, gas, petrochemical, and chemical industries.

Published: September 2022

Thin Al foils are promising materials for applications in devices of microelectromechanical systems (MEMS). In this work, three foils of high purity (5N) Al with different thickness (10, 50, and 125 μm) were analyzed by means of X‐ray photoelectron spectroscopy (XPS), before and after annealing (720 K for 30 min). XPS surface analysis and depth profiling of chemical composition were performed to investigate the distribution of Al oxide. Electron energy loss spectroscopy (EELS) measurements were also carried out in order to identify the plasmon losses and chemical state of Al. The loss peaks in the 5N‐Al thin foils were compared with those of an Al foil of commercial purity (99.95 wt%). The thickness of the oxide layer on the sample surface of all the samples is not constant and oxide is thicker in the samples of high purity than in those of commercial quality. Moreover, the thinnest foils of 5N‐Al (10 μm) exhibit the thinnest oxide layer. These findings have been discussed by considering the size effect, that is, mechanical properties of thin foils are improving as the thickness decreases. The complex morphology of the metal‐oxide interface may contribute to enhance the mechanical performances of Al foils with a thickness below ~50 μm, because the free dislocations pile up against the interface which represents an obstacle for their motion hindering plastic deformation. Obtained results suggest that Al foils to be used in MEMS devices should be of high purity and annealed to get a surface completely covered by the oxide layer.

AbstractSuperhydrophobic surfaces with the “lotus effect” have wide applications in daily life and industry, such as self‐cleaning, anti‐freezing, and anti‐corrosion. However, it is difficult to reliably predict whether a designed superhydrophobic surface has the “lotus effect” by traditional theoretical models due to complex surface topographies. Here, a reliable machine learning (ML) model to accurately predict the “lotus effect” of solid surfaces by designing a set of descriptors about nano‐scale roughness and micro‐scale topographies in addition to the surface hydrophobic modification is demonstrated. Geometrical and mathematical descriptors combined with gray level cooccurrence matrices (GLCM) offer a feasible solution to the puzzle of accurate descriptions of complex topographies. Furthermore, the “black box” is opened by feature importance and Shapley‐additive‐explanations (SHAP) analysis to extract waterdrop adhesion trends on superhydrophobic surfaces. The accurate prediction on as‐fabricated superhydrophobic surfaces strongly affirms the extensionality of the ML model. This approach can be easily generalized to screen solid surfaces with other properties.

Published: September 2022

AbstractElectrocatalysis plays a fundamental role in many fields, such as metallurgy, medicine, chemical industry, and energy conversion. Anchoring active electrocatalysts with controllable loading and uniform dispersion onto suitable supports has become an attractive topic. This is because the supports can not only have the potential to improve catalytic activity and stability through the interaction between support and catalytic center, but also can reduce precious metal consumption by improving atomic utilization. Herein, recent theoretical and experimental progresses concerning the development of supports to anchor electrocatalytic materials are first reviewed. Next, their controllable syntheses, characterization techniques, metal‐support electronic interactions, and structure‐performance relationships are presented. Some representative carbon supports and non‐carbonaceous supports, as well as recently reported star supports such as 2D supports, single atom catalysts, and self‐supported catalysts are also summarized. In addition, the significant role of support in stabilizing and regulating catalytic active sites is particularly emphasized. Finally, challenges, opportunities, key problems, and further promising solutions for supported catalysts are proposed.

AbstractA magnetic porous carbon NH2‐MIL‐101‐C was synthesized through a one‐step carbonization process using NH2‐MIL‐101(Fe) as the precursor. The morphology, structure, magnetic behavior, and porosity of the as‐prepared NH2‐MIL‐101‐C were characterized. The results show that NH2‐MIL‐101‐C has a high Brunauer‐Emmett‐Teller surface area (213.7 m2/g), a large pore volume (0.2 m3/g), and a good magnetic property (23.4 emu/g). The NH2‐MIL‐101‐C was first used as a magnetic solid‐phase extraction adsorbent for the extraction of five anthraquinones from rhubarb. The main parameters that will affect the extraction efficiency were investigated. Under the optimized conditions, good linearity for the five anthraquinones was obtained with the R2 higher than 0.9910. The limits of detection and limits of quantitation for the analytes are 0.018−0.042 and 0.050−0.140 μg/mL, respectively.

Published: September 2022

AbstractSimulating the contribution of masonry infills on the reaction of reinforced concrete (RC) frames have been the concentration point of numerous numerical studies. However, the effects of openings are often neglected by technical codes, which may lead to sensible errors in predicting the seismic behavior of masonry infilled frames. In this study, the simplified macromodeling approaches of equivalent diagonal strut model (EDSM) and two‐dimensional discrete macroelement model (DMEM) compared to a finite element model (FEM) and the influence of the modeling approach on the lateral response of infilled frames, with different percentages of openings, was investigated. A nonlinear static pushover analysis for conveying the terms of the monotonic loading procedure of the benchmark experimental program has been employed. Concerning the results, the stiffness of the masonry infilled frames by increasing the amount of opening was decreasing. The outcomes of this study may increase the knowledge of comparing the possible methods for modeling masonry infilled frames with openings.
