Published: July 2023

BackgroundNative T1 and radiomics were used for hypertrophic cardiomyopathy (HCM) and hypertensive heart disease (HHD) differentiation previously. The current problem is that global native T1 remains modest discrimination performance and radiomics requires feature extraction beforehand. Deep learning (DL) is a promising technique in differential diagnosis. However, its feasibility for discriminating HCM and HHD has not been investigated.PurposeTo examine the feasibility of DL in differentiating HCM and HHD based on T1 images and compare its diagnostic performance with other methods.Study TypeRetrospective.Population128 HCM patients (men, 75; age, 50 years ± 16) and 59 HHD patients (men, 40; age, 45 years ± 17).Field Strength/Sequence3.0T; Balanced steady‐state free precession, phase‐sensitive inversion recovery (PSIR) and multislice native T1 mapping.AssessmentCompare HCM and HHD patients baseline data. Myocardial T1 values were extracted from native T1 images. Radiomics was implemented through feature extraction and Extra Trees Classifier. The DL network is ResNet32. Different input including myocardial ring (DL‐myo), myocardial ring bounding box (DL‐box) and the surrounding tissue without myocardial ring (DL‐nomyo) were tested. We evaluate diagnostic performance through AUC of ROC curve.Statistical TestsAccuracy, sensitivity, specificity, ROC, and AUC were calculated. Independent t test, Mann–Whitney U‐test and Chi‐square test were adopted for HCM and HHD comparison. P < 0.05 was considered statistically significant.ResultsDL‐myo, DL‐box, and DL‐nomyo models showed an AUC (95% confidential interval) of 0.830 (0.702–0.959), 0.766 (0.617–0.915), 0.795 (0.654–0.936) in the testing set. AUC of native T1 and radiomics were 0.545 (0.352–0.738) and 0.800 (0.655–0.944) in the testing set.Data ConclusionThe DL method based on T1 mapping seems capable of discriminating HCM and HHD. Considering diagnostic performance, the DL network outperformed the native T1 method. Compared with radiomics, DL won an advantage for its high specificity and automated working mode.Level of Evidence4Technical Efficacy Stage2

Published: July 2023

IntroductionAlthough microlaryngoscopy has been recognized to be effective in addressing lesions in vocal performers, no detailed information regarding return to performance (RTP) following surgery exists. We describe our experience and offer proposals to establish standardized criteria for RTP among vocal performers.MethodsRecords for adult vocalists who underwent microlaryngoscopy for benign vocal fold (VF) lesions and had a clearly documented RTP date between 2006 and 2022 were reviewed. Patient demographics, diagnoses, interventions, and postsurgical care before and after RTP were described. The need for medical and procedural interventions and rate of reinjury were used to determine the success of RTP.ResultsSixty‐nine vocal performers (average age: 32.8 years, 41 [59.4%] female, 61 [88.4%] musical theater) underwent surgery for 37 (53.6%) pseudocysts, 25 (36.2%) polyps, 5 (7.2%) cysts, 1 (1.4%) varix, and 1 (1.4%) mucosal bridge. Fifty‐seven (82.6%) underwent voice therapy. The average time to RTP was 65.0 ± 29.8 days. Prior to RTP, six (8.7%) experienced VF edema requiring oral steroids and one (1.4%) underwent a VF steroid injection. Within 6 months following RTP, eight (11.6%) received oral steroids for edema and three underwent procedural interventions (two steroid injections for edema/stiffness, one injection augmentation for paresis). One patient experienced pseudocyst recurrence.ConclusionsReturn to vocal performance at an average of 2 months following microlaryngoscopy for benign lesions appears overwhelmingly successful, with low rates of need for additional intervention. There is a need for validated instruments to better measure performance fitness to refine and possibly accelerate RTP.Level of Evidence4 Laryngoscope, 134:329–334, 2024

AbstractIntroductionImplementation of research findings in clinical practice often is not realized or only partially achieved, and if so, with a significant delay. Learning health systems (LHSs) hold promise to overcome this problem by embedding clinical research and evidence‐based best practices into care delivery, enabling innovation and continuous improvement. Implementing an LHS is a complex process that requires participation and resources of a wide range of stakeholders, including healthcare leaders, clinical providers, patients and families, payers, and researchers. Engaging these stakeholders requires communicating clear, tangible value propositions. Existing models identify broad categories of benefits but do not explicate the full range of benefits or ways they can manifest in different organizations.MethodsTo develop such a framework, a working group with representatives from six Clinical and Translational Science Award (CTSA) hubs reviewed existing literature on LHS characteristics, models, and goals; solicited expert input; and applied the framework to their local LHS experiences.ResultsThe Framework of LHS Benefits includes six categories of benefits (quality, safety, equity, patient satisfaction, reputation, and value) relevant for a range of stakeholders and defines key concepts within each benefit. Applying the framework to five LHS case examples indicated preliminary face validity across varied LHS approaches and revealed three dimensions in which the framework is relevant: defining goals of individual LHS projects, facilitating collaboration based on shared values, and establishing guiding tenets of an LHS program or mission.ConclusionThe framework can be used to communicate the value of an LHS to different stakeholders across varied contexts and purposes, and to identify future organizational priorities. Further validation will contribute to the framework's evolution and support its potential to inform the development of tools to evaluate LHS impact.

Published: July 2023

AbstractWith businesses under increasing pressure to provide excellent customer service, postfailure recovery strategies have become critical for long‐term customer satisfaction and loyalty. The domain of service recovery has extensively been examined in academia; however, systematic studies that provide a consolidated overview remains scant. To this end, we provide a systematic review and synthesis of service recovery literature by conducting a bibliometric‐based cocitation analysis of 24,741 cited references from 1020 articles from across disciplines. The study identifies 10 major research clusters that represent different research streams of service recovery and explores their intellectual foundations. In addition, the research presents a conceptual framework to serve as a parsimonious guide for both practitioners and researchers. Furthermore, the study reveals a number of gaps in the existing literature and suggests promising directions for further investigation, including but not limited to: expanding methodological horizons in service recovery research, understanding service recovery mechanisms in Metaverse and synthetic environments, globalizing service recovery research, revitalizing service recovery processes in the age of artificial intelligence and robotics, investigating service recovery as an investment, and exploring service recovery in shared economies. Notably, this study serves managers, firstly, by providing them with a parsimonious structure of service recovery field that could help identify areas of improvement in their own service recovery systems and, secondly, by highlighting areas where academic knowledge base could inform industry solutions.

Published: July 2023

AbstractMicroorganisms are known to be natural agents of biocorrosion and mineral transformation, thereby potentially affecting the safety of deep geological repositories used for high‐level nuclear waste storage. To better understand how resident microbial communities of the deep terrestrial biosphere may act on mineralogical and geochemical characteristics of insulating clays, we analyzed their structure and potential metabolic functions, as well as site‐specific mineralogy and element composition from the dedicated Mont Terri underground research laboratory, Switzerland. We found that the Opalinus Clay formation is mainly colonized by Alphaproteobacteria, Firmicutes, and Bacteroidota, which are known for corrosive biofilm formation. Potential iron‐reducing bacteria were predominant in comparison to methanogenic archaea and sulfate‐reducing bacteria. Despite microbial communities in Opalinus Clay being in majority homogenous, site‐specific mineralogy and geochemistry conditions have selected for subcommunities that display metabolic potential for mineral dissolution and transformation. Our findings indicate that the presence of a potentially low‐active mineral‐associated microbial community must be further studied to prevent effects on the repository's integrity over the long term.
Nonlinear approximation of functions based on nonnegative least squares solver
Authors: Vabishchevich Petr N. 
Published: July 2023

AbstractIn computational practice, most attention is paid to rational approximations of functions and approximations by the sum of exponents. We consider a wide enough class of nonlinear approximations characterized by a set of two required parameters. The approximating function is linear in the first parameter; these parameters are assumed to be positive. The individual terms of the approximating function represent a fixed function that depends nonlinearly on the second parameter. A numerical approximation minimizes the residual functional by approximating function values at individual points. The second parameter's value is set on a more extensive set of points of the interval of permissible values. The proposed approach's key feature consists in determining the first parameter on each separate iteration of the classical nonnegative least squares method. The computational algorithm is used to rational approximate the function . The second example concerns the approximation of the stretching exponential function at by the sum of exponents.
Testing how information about cost‐effectiveness, cause preferences, and geographic preferences interact to affect philanthropic giving
Authors: Taggart Gabel , Cooper Kathryn E. 
Published: July 2023

AbstractThe broad instrumental philanthropy movement advocates for considerations of cost‐effective impact in donation decisions. Within that broader movement, the effective altruism movement goes as far as to advocate for cause neutrality and geographic neutrality when prioritizing cost‐effectiveness in charity. We present a survey experiment that examined how information about cost‐effectiveness, cause area preferences, and geographic preferences interact to affect philanthropic giving. The experiment varied these three dimensions in a hypothetical giving situation and found that cost‐effectiveness information had the strongest influence on hypothetical giving. Participants gave most when presented with charities that were shown to be highly cost‐effective, local/domestic, and that matched their preferred cause area. Understanding how these three considerations interact to affect donors is important as donors continue to desire more information about the cost‐effective impact of their donation.

Published: July 2023

AbstractElectromagnetic radiation interference (EMI) or pollution is increased significantly in proportion to the expansion of electronic and communication industries, which lead to the disturbance of the functioning of electronic gadgets and medical equipments, in addition to the human health damage. The Microwave absorbing (MA) composite comprised of polyvinyl alcohol (PVA), polyaniline (PANI), carbon nanotube (MWCNT) and iron oxide (Fe3O4) has been developed with various proportions, denoted as PVA/PANI/MWCNT/Fe3O4 (1%, 3%, 5%). Fe3O4 was prepared using a hydrothermal method, and PVA/PANI/MWCNT/Fe3O4 (1%, 3%, 5%) nanocomposites was made by solvent casting techniques. The PVA composite films were also subjected to a range of analyses including IR, TGA, DTA, DTG, SEM, TEM, dielectric measurements and EMI shielding effectiveness (EMI SE), to describe their characteristics. The results of various studies indicate that the PVA/PANI/MWCNT/Fe3O4 (1%, 3%, 5%) composites possess enhanced thermal and dielectric characteristics, for instance the PVA/PANI/MWCNT/5% Fe3O4 blend nanocomposites possess 10% initial decomposition at 220°C and dielectric constant of 3.2 × 107 at 1 MHz. The total EMI SE value for the synthetic PVA/PANI/MWCNT/Fe3O4 was found at 9.2 and 10 GHz is 48 and 54 dB, respectively, exhibiting synergistic properties of the composites toward EMI shielding. The microwave absorption spectra indicate two absorption peaks in the region around 8 to 12 GHz, with the absorption reflection loss (RL) value of −20 dB at 10 GHz for the PVA/PANI/MWCNT/5% Fe3O4 nanocomposites.
Preparation and application of ZIF‐67/gelatin porous composite membrane via high internal phase emulsion

Published: July 2023

AbstractThe high internal phase emulsion (HIPE) template method is widely used to prepare porous functional materials because of its designable emulsion components and adjustable porosity. Herein, amphiphilic gelatin (GE) as the sole emulsion stabilizer, and no additional emulsifiers were added to prepare a stable GE‐HIPE membrane and its zeolitic imidazolate framework‐67 (ZIF‐67) hybrid composite membrane. The ZIF‐67/GE‐HIPE composite membrane has good lipophilicity by constructing dual micro‐nano structures by HIPE template and in situ growth of ZIF‐67. When ZIF‐67 was grown in situ, the water contact angle (CA) increased from 58.1 ± 2° for the GE membrane to 121 ± 1.9° for ZIF‐67/GE‐HIPE composite membranes. Besides, the minimum CA of organic solvent is 4.5 ± 0.7° (n‐hexane). The ZIF‐67/GE‐HIPE composite membranes exhibit good O/W emulsion separation properties and adsorption removal ability of organic pollutants. After 10 times of recycling emulsion separation, the emulsion separation capacity of the membrane was still greater than 99.4%. The lipophilic dye removal rate of the ZIF‐67/GE‐HIPE composite membrane was 2.37 times higher than that of GE‐HIPE, and the adsorption process conforms to the pseudo‐second‐order model. Thus, this work provides a strategy for the preparation of GE‐based hydrophobic modified membrane and also presents a typical treatment of adsorption‐separation of lipophilic substances.

AbstractFlax fiber‐reinforced polymer (FFRP) composites are emerging popular environmental‐friendly construction materials. However, their significant creep properties have been a major concern for using FFRP in load‐bearing structures. This article presents an investigation of the effect of environmental humidity on the creep behavior of the FFRP. Samples with flax fiber in 0°, 90°, and ± 45° were manufactured, respectively, by the vacuum infusion method. Accelerated creep tests were conducted on samples in different relative humidities (RH), and the results were analyzed by the time–temperature superposition principle (TTSP). It is found the creep development of samples with 0° and 90° fiber increases with the RH, and their 30‐year total strain in 97% RH is about 10 times higher than that in 11% RH. The samples with ±45° fiber are found not obviously sensitive to the humidity change. The scanning electron microscope (SEM) check indicates the change in the fiber–matrix interface and cracks between microfibrils in a fiber bundle is the main reason for the change of creep behavior in high humidity. This study may benefit the design of structures made of natural fiber‐reinforced polymer composites, especially for load‐bearing structures working in high‐humidity environments.
The factor structure of mathematics anxiety and its relation to gender and mathematics performance
Authors: Namkung Jessica M. , Goodrich J. Marc , Lee Kejin 
Published: July 2023

AbstractMathematics anxiety (MA) refers to negative cognition and negative affect that interfere with mathematics performance. We examined the dimensionality of MA, measurement invariance across males and females, and whether the strength of relations between MA and mathematics performance varies by dimension and gender among 245 sixth‐grade students. Students were assessed on MA, arithmetic fluency, and on‐grade‐level computation skills. The confirmatory factor analysis and measurement invariance tests indicated that two distinct dimensions, cognition and affect, best represent MA across both genders. For the full sample, on‐grade‐level computation skills showed a significant negative relation with the cognitive dimension only, whereas arithmetic fluency was not significantly related to either dimension. We did not find any significant gender differences. Our findings provide support for the cognitive and affective model of MA and negative impact of MA on mathematics performance. Our findings further suggest incorporating the cognitive component in identifying and alleviating MA, and improving mathematics outcomes.
Genetic evidence that brassinosteroids suppress pistils in the maize tassel independent of the jasmonic acid pathway
Authors: Best Norman , Dilkes Brian 
Published: July 2023

AbstractThe developmental genetics of reproductive structure control in maize must consider both the staminate florets of the tassel and the pistillate florets of the ear synflorescences. Pistil abortion takes place in the tassel florets, and stamen arrest is affected in ear florets to give rise to the monoecious nature of maize. Gibberellin (GA) deficiency results in increased tillering, a dwarfed plant syndrome, and the retention of anthers in the ear florets of maize. The silkless1 mutant results in suppression of silks in the ear. We demonstrate in this study that jasmonic acid (JA) and GA act independently and show additive phenotypes resulting in androecious dwarf1;silkless1 double mutant plants. The persistence of pistils in the tassel can be induced by multiple mechanisms, including JA deficiency, GA excess, genetic control of floral determinacy, and organ identity. The silkless1 mutant can suppress both silks in the ear and the silks in the tassel of JA‐deficient and AP2 transcription factor tasselseed mutants. We previously demonstrated that GA production was required for brassinosteroid (BR) deficiency to affect persistence of pistils in the tassel. We find that BR deficiency affects pistil persistence by an independent mechanism from the silkless1 mutant and JA pathway. The silkless1 mutant did not prevent the formation of pistils in the tassel by nana plant2 in double mutants. In addition, we demonstrate that there is more to the silkless1 mutant than just a suppression of pistil growth. We document novel phenotypes of silkless1 mutants including weakly penetrant ear fasciation and anther persistence in the ear florets. Thus, the JA/AP2 mechanism of pistil retention in the tassel and silk growth in the ear are similarly sensitive to loss of the SILKLESS1 protein, while the BR/GA mechanism is not.

Published: July 2023

AbstractBackgroundCaregivers play an important role supporting people diagnosed with cancer, yet report significant unmet information and support needs that impact on their psychological wellbeing. Health literacy and social connectedness are key factors that influence wellbeing, yet few studies have examined their relative role in psychological wellbeing of carers. This study investigated relationships between caregiver and care recipient health literacy, social support, and social connectedness on psychological morbidity in a cancer setting.MethodsThis cross‐sectional study included 125 caregiver‐cancer care recipient dyads. Participants completed the Health Literacy Survey‐EU‐Q16, Social Connectedness Scale‐Revised, the Medical Outcomes Study–Social Support Survey, and the Depression, Anxiety and Stress Scale‐21 (DASS21). Relationships between factors were examined using hierarchical multiple regression with care recipient factors entered at Step 1 and caregiver factors at Step 2.ResultsMost caregivers provided care for their spouse (69.6%); caregivers mean total DASS21 score was 24.38 (SD = 22.48). Mean DASS21 subscale scores for depression, anxiety, stress in caregivers were 4.02 (SD = 4.07), 2.7 (SD = 3.64), and 5.48 (SD = 4.24) respectively, suggesting normal range of depression and stress, and mild anxiety. Care recipients had a diagnosis of breast (46.4%), gastrointestinal (32.8%), lung (13.6%), or genitourinary (7.2%) cancer, and a mean DASS21 score of 31.95 (SD = 20.99). Mean DASS21 subscale scores for depression, anxiety, stress in care recipients were 5.10 (SD = 4.18), 4.26 (SD = 3.65), and 6.62 (SD = 3.99) respectively, suggesting mild depression and anxiety, and normal stress scores. Regression analyses showed that only caregiver factors (age, illness/disability, health literacy and social connectedness) were independent predictors of caregiver psychological morbidity (F [10,114] = 18.07, p < 0.001).Conclusion(s)Only caregiver, and not care recipient, factors were found to influence caregiver psychological morbidity. While both health literacy and social connectedness influenced caregiver psychological morbidity, perceived social connectedness had the strongest influence. Interventions that ensure caregivers have adequate health literacy skills, as well as understand the value of social connection when providing care, and are supported to develop skills to seek support, have the potential to promote optimal psychological wellbeing in cancer caregivers.
