Published: September 2023

AbstractThermoplastic vulcanizates (TPVs) are obtained by dynamic vulcanization (DV). Time is a crucial processing parameter. This work aims to develop heat‐ and oil‐resistant TPVs with hydrogenated acrylonitrile butadiene rubber (HNBR) and thermoplastic polyester elastomer (TPEE). It focuses on the effect of DV time on the morphology and properties of the resulting TPVs. The investigation demonstrates that as the DV time increases from 2 to 6 min, the rubber network progressively reinforces and the HNBR domain size decreases under more adequate shearing action, resulting in a more homogeneous morphology. This leads to a significant improvement in tensile properties, elasticity, rheological properties, thermal stability, and oil resistance of the TPV. A further extension in DV time (over 8 min) results in a slight deterioration in elasticity and thermal stability of the TPV because of excessive degradation of the TPEE. Accordingly, an appropriate DV time for HNBR/TPEE‐TPV preparation is between 6 and 8 min under the specified DV conditions.

AbstractDue to its comprehensive properties, polyurethane elastomer (PU) plays a vital role in ships, construction, transportation facilities, and other fields. However, it is challenging to design polyurethane elastomer materials with good mechanical properties, self‐healing ability, and degradable ability. Herein, a kind of polyurethane elastomer based on multiple hydrogen bond crosslinking was successfully synthesized by using polycaprolactone with substantial crystallization as a soft chain segment and introducing adipic dihydrazide (ADH) and U2‐diol (a ureido‐pyrimidinone with two hydroxyl groups at the end) to achieve ordered hydrogen bond assembly design and control. The elastomer has good tensile strength, healability, degradability, and solubility. The maximum tensile strength and toughness of the prepared polyurethane elastomer (PUAD) were 46.34 MPa and 687.66 MJ/m3, respectively. With the increase of U2‐diol content, the self‐repair efficiency was greatly enhanced. After seven repair cycles, the self‐repair efficiency can still reach 66.88%. In addition, the bacterial degradation test using Pseudomonas aeruginosa as a strain showed that PUAD film had excellent degradability. The dissolution test with N,N‐dimethylformamide (DMF) as solvent showed that the tensile strength was almost unchanged after three dissolutions.

Published: September 2023

AbstractCurrently, over 500 rare genetic bone disorders are identified. These diseases are often accompanied by dental abnormalities, which are sometimes the first clue for an early diagnosis. However, not many dentists are sufficiently familiar with phenotypic abnormalities and treatment approaches when they encounter patients with rare diseases. Such patients often need dental treatment but have difficulties in finding a dentist who can treat them appropriately. Herein we focus on major dental phenotypes and summarize their potential causes and mechanisms, if known. We discuss representative diseases, dental treatments, and their effect on the oral health of patients and on oral health‐related quality of life. This review can serve as a starting point for dentists to contribute to early diagnosis and further investigate the best treatment options for patients with rare disorders, with the goal of optimizing treatment outcomes.

AbstractBackgroundImmune checkpoint inhibitors have revolutionized the treatment of malignancies. However, disproportionate enrollment among races and ethnicities places the generalizability of global trial results in doubt.MethodsIn this systematic review, phase 3 randomized controlled trials investigating pembrolizumab in advanced cancers and providing subgroup analyses of Asian and non‐Asian participants were included. The primary and secondary effect measures were the mean differences (MDs) in the natural logarithms of the hazard ratios (HRs) for overall survival (OS) and progression‐free survival (PFS) between these two subgroups, respectively. We used random‐effects meta‐analysis to calculate the pooled ratios of HRs (i.e., exp(MD)) and implemented a meta‐regression analysis to identify significant covariates.ResultsA total of 17 and 11 trials were included in the meta‐analyses of OS and PFS, respectively. These trials included 2732 (25.49%) Asian and 7000 (65.32%) non‐Asian participants in the OS analysis and 1438 (22.5%) Asian and 4129 (64.61%) non‐Asian participants in the PFS analysis. The pooled ratio of HRs for OS was 0.87 (95% CI: 0.76–0.99; p = 0.0391), favoring Asian participants, but no significant difference was found in PFS (pooled ratio of HRs: 0.93; 95% CI: 0.82–1.07; p = 0.2391). Both linear meta‐regression analyses revealed an open‐label design as a crucial covariate, which indicated more benefits for non‐Asian participants.ConclusionsCompared with non‐Asian patients, Asian patients with advanced cancers may derive superior OS benefits from pembrolizumab. Although the results warrant further exploration, this meta‐analysis provides insight into clinical research design.

AbstractUltra‐light buyers, those who, on average, buy a brand once a year or less, are important by number and their contribution to brand purchase occasions. The initial research, however, was limited in scope and did not measure the contribution of these buyers to sales volume or value. By examining over 850 brands in almost 60 categories, we identify that ultra‐lights make up 62% of a brand's buyer base over 5 years and contribute 32% of purchase occasions and 31% of sales volume and value. In line with previous findings that brands with higher loyalty exhibit more repeat purchases and thus fewer ultra‐light buyers and private label brands often exhibit higher than expected loyalty for their market share—we find the prevalence of ultra‐light buyers is higher for national brands than private labels, likely reflecting the higher loyalty often observed for private labels. We also find no difference in ultra‐light buyers' contribution between high and low‐price brands, indicating that price is not a significant factor affecting the contribution of ultra‐light buyers. Finally, we find that both growing and declining brands have fewer ultra‐lights than stable brands. As growth occurs via increasing penetration and loyalty, for growing brands, new buyers may be more ‘light’ than ‘ultra‐light’ in terms of their loyalty; while for declines, these findings imply that there are not enough ultra‐light buyers to maintain brand sales. A failure to recruit ultra‐light buyers may be very dangerous for brand health.

AbstractObjectivesWe sought to produce a simple scoring system that can be applied at clinical visits before transcatheter aortic valve replacement (TAVR) to stratify the risk of permanent pacemaker (PPM) after the procedure.BackgroundAtrioventricular block is a known complication of TAVR. Current models for predicting the risk of PPM after TAVR are not designed to be applied clinically to assist with preprocedural planning.MethodsPatients undergoing TAVR at the University of Colorado were split into a training cohort for the development of a predictive model, and a testing cohort for model validation. Stepwise and binary logistic regressions were performed on the training cohort to produce a predictive model. Beta coefficients from the binary logistic regression were used to create a simple scoring system for predicting the need for PPM implantation. Scores were then applied to the validation cohort to assess predictive accuracy.ResultsPatients undergoing TAVR from 2013 to 2019 were analyzed: with 483 included in the training cohort and 123 included in the validation cohort. The need for a pacemaker was associated with five preprocedure variables in the training cohort: PR interval > 200 ms, Right bundle branch block, valve‐In‐valve procedure, prior Myocardial infarction, and self‐Expandable valve. The PRIME score was developed using these clinical features, and was highly accurate for predicting PPM in both the training and model validation cohorts (area under the curve 0.804 and 0.830 in the model training and validation cohorts, respectively).ConclusionsThe PRIME score is a simple and accurate preprocedural tool for predicting the need for PPM implantation after TAVR.
Autocatalysis and CO2: Carbon Capture and Utilization (CCU) Meets Natural Processes

Published: September 2023

AbstractAutocatalytic reactions were proposed to play a key role at the beginning of life starting from the first reduction of CO2 to formate, acetate and C1−C4 hydrocarbons. In carbon capture and utilization (CCU) processes, the same reactions were demonstrated to be autocatalytic and, in some cases, promoted by catalysts of the same composition. Through evolution, CO2 reduction then turned into complex autocatalytic networks such as photosynthesis, where CCU chemists found inspiration for the development of more advanced systems for the synthesis of value‐added chemicals. Less evolved systems than photosynthesis, however, may be easier to emulate and provide valuable inspiration into CO2 reduction chemistry for CCU. Other synthetic systems were also demonstrated to be autocatalytic demonstrating that CO2 reactions and autocatalysis are closely connected. In this concept article, the relationship between natural, artificial and bio‐inspired autocatalytic CO2 reduction processes is summarized and discussed. The accomplishments resulting from the integration of autocatalysis and CCU strategies, along with their inherent benefits and future prospectives are also outlined.

AbstractA synthetic strategy is demonstrated to prepare two distinct trimers of antiferromagnetically coupled {Cr7Ni} rings, substantially varying the magnetic interactions between the spin centres. The interactions were studied using multi‐frequency cw EPR: in a trimer linked via non‐covalent H‐bonding interactions no measurable interaction between rings was seen, while in a trimer linked via iso‐nicotinate groups isotropic and anisotropic exchange interactions of +0.42 and −0.8 GHz, respectively, were observed. The latter are the same as those for a simpler hetero‐dimer system, showing how the spin‐spin interactions can be built in a predictable and modular manner in these systems.
Decoding a drawing: The stained‐glass color scheme of the altar of Igreja de Nossa Senhora de Fátima
Authors: Palmeirim Simão 
Published: September 2023

AbstractIn the process of cataloging the estate of modernist artist Almada Negreiros, many preparatory drawings for several of the author's public artworks are currently being identified. The volume and complexity of his prolific work imply that sometimes it is hard to connect specific documents and artworks of research and preparation to their respective final works. Recently, one particular drawing proved to be the key for understanding several other documents, simultaneously contributing to clarify the artist's methodology when preparing for the large‐scale stained glass behind the altar of Igreja de Nossa Senhora de Fátima. This article presents these new advances.

AbstractColor significantly shapes our perceptions of the world, and extensive scientific research has explored various aspects of color, including color linguistics, aesthetics, color and marketing, color therapy, and color psychology. Notably, there has been an increasing interest in understanding the psychological domain of color in recent years. However, limited scholarly attention has been given to studying the changes in color representations and emotions over the decades. To address this gap, we utilized word embedding models of Google Books Ngrams corpus to examine the most strongly associated entities and traits with colors and their evolution in color emotions over 200 years. Analyzing three emotional dimensions—pleasure, arousal, and dominance (PAD), we found that red, green, white, black, orange, purple, brown, and pink were related to the exuberant type (+P + A + D) in PAD emotional space. In contrast, blue was linked to the relaxed type (+P−A + D), and yellow constituted the anxious type (−P + A−D). Among all basic English color terms, the emotion‐driven perceptions associated with white, brown, and pink have significantly changed over time.

AbstractConsider the tight binding model of graphene, sharply terminated along an edgelparallel to a direction of translational symmetry of the underlying period lattice. We classify such edgeslinto those of “zigzag type” and those of “armchair type”, generalizing the classical zigzag and armchair edges. We prove that zero energy / flat band edge states arise for edges of zigzag type, but never for those of armchair type. We exhibit explicit formulas for flat band edge states when they exist. We produce strong evidence for the existence of dispersive (non flat) edge state curves of nonzero energy for mostl.
Promoting sustainable development: Multiple mediation effects of green value co‐creation and green dynamic capability between green market pressure and firm performance

Published: September 2023

AbstractThe need for organizations to safeguard and advance environmental sustainability has recently become imperative due to mounting pressures from various stakeholder groups. However, a significant research gap remains regarding how these pressures influence enterprises' green practices and performance. The aim of this study is to examine the impact of green market pressure exerted by customers and competitors on firm performance, taking into account the multiple mediating effects of green value co‐creation and green dynamic capability. Questionnaire survey data collected from 274 high‐tech manufacturing companies in the Yangtze River Delta of China were used to test the proposed relationships. By testing the mediation effects based on stakeholder theory and dynamic capability view, the results show that green market pressure positively affects firm performance, while both green value co‐creation and green dynamic capability play as an individual mediator between green market pressure and firm performance. Moreover, green value co‐creation and green dynamic capability sequentially mediate the link between green market pressure and firm performance. These findings provide valuable suggestions for improving firm performance under the background of environmental protection.
Framing as a strategy for defending the perceived authenticity of voluntary environmental disclosure in the digital era
Authors: Lv David , Wokutch Richard 
Published: September 2023

AbstractIn the digital age, to attract readers' attention, environmental activists may change the way corporate environmental information is reported and reinterpret it in social media. This paper aims to discuss how firms protect the perceived authenticity of their environmental disclosure. This study suggests that framing enables firms to clarify the disclosure focus for their readers in the information‐overload context. We propose five framing strategies and evaluate their effects on the stigmatized categorization, attribution, and diffusion of environmental information. By doing so, we add framing strategies to the managerial toolkit available for protecting the perceived authenticity of corporate voluntary environmental disclosure.

Published: September 2023

AbstractObjectiveLittle is known about how individuals with atypical anorexia nervosa (AN) respond to eating disorder (ED) treatment in a partial hospitalization program (PHP), nor how certain factors such as trauma, childhood abuse, psychiatric comorbidity, and suicidal thoughts and behaviors might contribute to poor treatment outcomes. Thus, the current study (1) compares prevalence of these factors between individuals with AN and atypical AN upon admission to an ED PHP, (2) compares PHP treatment response between groups, and (3) investigates whether experiencing these factors impacts treatment outcomes.MethodWe conducted a retrospective chart review of young adults admitted to a PHP with AN (n = 95) and atypical AN (n = 59). Histories of psychiatric comorbidities and adverse childhood experiences were obtained from initial psychiatric evaluations. ED symptoms were assessed at intake and discharge with the Eating Disorder Examination‐Questionnaire (EDE‐Q).ResultsNo significant differences were found at intake in ED symptom severity or prevalence of lifetime trauma, childhood abuse, number of psychiatric diagnoses, or suicidal thoughts and behavior. Symptomatology at discharge also did not differ between groups. Emotional abuse was significantly related to discharge shape and weight overvaluation. No other intake characteristics were significantly related to discharge symptomatology.DiscussionTo our knowledge, this is the first study to compare the prevalence of comorbidities for both AN and atypical AN, as well as differential treatment outcomes for these individuals in a PHP. Results add to growing literature suggesting that, other than weight, AN and atypical AN have few properties that reliably distinguish them from one another.Public SignificanceThis study adds to a growing body of literature that raises questions about whether anorexia nervosa (AN) and atypical AN are truly different diagnoses. Our findings suggest these two groups present to treatment in a partial hospitalization program (PHP) with similar ED symptoms, as well as prevalence of lifetime trauma, childhood abuse, suicidal thoughts and behavior, and number of psychiatric comorbidities, and demonstrate similar treatment trajectories in PHP.

AbstractAimsObservational evidence suggests associations between sex hormone levels and heart failure (HF). We used sex‐specific genetic variants associated with androgenic sex hormone profiles to investigate the causal relevance of androgenic sex hormone profiles on cardiac structure and function and HF using Mendelian randomization (MR).Methods and resultsSex‐specific uncorrelated genome‐wide significant (P < 5 × 10−8) variants predicting sex hormone‐binding globulin (SHBG), total testosterone, and bioavailable testosterone were extracted from summary statistics of genome‐wide association study (GWAS) on 425 097 participants in the UK Biobank. Sex‐specific gene–outcome association estimates were computed for left ventricular ejection fraction (LVEF), left ventricular end‐diastolic and end‐systolic volumes (LVEDV and LVESV, respectively), left ventricular stroke volume (LVSV), cardiac index, and cardiac output in 11 528 female and 14 356 male UK Biobank Imaging Study participants and for incident or prevalent HF in an external cohort of 47 309 cases and 930 014 controls. Inverse‐variance weighted MR was the primary analysis method. In females, higher genetically predicted bioavailable testosterone was associated with lower LVEDV [β per nmol/L = −0.11 (−0.19 to −0.03), P = 0.006], lower LVESV [β = −0.09 (−0.17 to −0.01), P = 0.022], lower LVSV [β = −0.11 (−0.18 to −0.03), P = 0.005], lower cardiac output [β = −0.08 (−0.16 to 0.00), P = 0.046], and lower cardiac index [β = −0.08 (−0.16 to −0.01), P = 0.034] and a higher risk of HF [odds ratio 1.10 (1.01–1.19), P = 0.026] on external validation analysis in larger scale, sex‐adjusted GWAS data. Higher genetically predicted SHBG was associated with higher LVEDV [β per nmol/L = 0.17 (0.08–0.25), P = 2 × 10−4], higher LVESV [β = 0.13 (0.05–0.22), P = 0.003], and higher LVSV [β = 0.18 (0.08–0.28), P = 2 × 10−4]. In males, higher genetically predicted total and bioavailable testosterone was associated with lower LVESV [β = −0.07 (−0.12 to −0.02), P = 0.007] and LVEF [β = −0.11 (−0.18 to −0.04), P = 0.003], respectively.ConclusionsThis study supports a causal effect of pro‐androgenic sex hormone profiles in females on adverse markers of left ventricular structure and function typically associated with HF with preserved ejection fraction and with HF. There was weaker evidence of association in males.
