• A Bi 7 O 9 I 3 /carbon paper composite was fabricated using an in-situ annealing method. • Flexible Bi 7 O 9 I 3 /carbon paper possesses hierarchical structure. • Bi 7 O 9 I 3 /carbon paper exhibited improved photocatalytic performance. • Improved carrier separation and hierarchical structure are key to performance enhancement. Although Bi 7 O 9 I 3 is an oxygen-rich bismuth oxyiodide with higher photocatalytic activity than BiOI, its applicability for photocatalytic oxidation is limited by the rapid recombination of photogenerated carriers and poor reusability. Depositing Bi 7 O 9 I 3 on flexible macro-sized carbonaceous materials is a promising approach for promoting photogenerated electron migration and improving reusability. In this study, a composite consisting of Bi 7 O 9 I 3 supported on graphitic carbon paper (Bi 7 O 9 I 3 -CP) was synthesized via the in situ transformation of a BiOI-deposited carbon paper precursor (BiOI-CP). The as-prepared Bi 7 O 9 I 3 -CP exhibited higher visible-light-driven photocatalytic activity than both Bi 7 O 9 I 3 and BiOI-CP precursor for phenol removal. The improved photocatalytic activity of Bi 7 O 9 I 3 -CP was attributed to its hierarchical structure and promoted carrier separation, as revealed by photoluminescence, pore structure, and reactive radical analyses. Moreover, owing to its macroscale size and flexibility, the Bi 7 O 9 I 3 -CP composite could be easily operated and reused, which are favorable for practical applications. [ABSTRACT FROM AUTHOR]

• Ultrathin and flexible paper with good EMI shielding performance is constructed. • Composite paper is featured with a three-layer structured surface. • TOCN/CS hydrogel film offers good protection for MXene. • TOCN/MXene with layered structure enhances the mechanical property of paper. MXene-contained paper is a good choice to design ultrathin and flexible electromagnetic interference (EMI) shielding materials. However, the deficiencies in strength and stability of MXene-contained paper impede its practical applications. Herein, a composite paper was proposed to address the problems, in which a filter paper was modified with a three-layer structured surface via a facile layer-by-layer coating procedure. Specifically, the TEMPO-oxidized cellulose nanofibers (TOCN)/cationic starch (CS)/MXene gel layer and TOCN/MXene nacre structure layer ensured the good EMI shielding and mechanical performances of the composite paper, while the uppermost TOCN/CS hydrogel film layer mainly protected MXene. The composite paper achieved an EMI SE of 40.3 dB at a thickness of merely 0.1894 mm (SE/ t value of ca. 212.8 dB mm−1, SSE/ t values of ca.13216 dB cm2 g−1) and the total MXene dosage was 20 g m−2. Its tensile strength could be up to 11.7 MPa while the original filter paper was 6.4 MPa. Four pieces of this composite papers could be easily packed together to attain an EMI SE of nearly 70 dB. Importantly, the hydrogel film layer efficiently protected the MXene and maintained the EMI shielding performance of the composite paper when immersed in different liquids including water, HCl (1 M) and ethanol, due to the dense and compact structure of hydrogel film layer. This work provides a practical way to develop ultrathin, flexible and durable EMI shielding materials. [Display omitted] [ABSTRACT FROM AUTHOR]

Keywords American Journal of surgery; Bibliometric analysis; Surgical history; Citation analysis Highlights * The 16 classic cited AJS papers were characterized. * Were based on careful clinical observations, innovation, and build on prior published work. * Citation recapitulated surgical history. Abstract Background We performed a bibliometric analysis of the American Journal of Surgery (AJS) to identify, characterize and place within a historical context, its published classic cited papers (CCPs). Methods Bibliometric data from papers published in the AJS between January 1, 1945, and December 31, 2021 was extracted from the Web of Science database. Analysis was performed utilizing Bibliometrix and VOSViewer software. Results 27,070 papers were published in the AJS over the study period. There were 16 CCPs, including 5 Top CCPs, identified. Review of the Top CCPs reveals that they are based on careful clinical observations, innovation and generally build on prior published work. Top CCPs usually are specific to a particular diagnosis or a commonly performed procedure, as such papers frequently present a scoring or classification system, or important details related to new operative approaches or techniques. Conclusions Bibliometric study of the AJS has allowed for identification, characterization and appreciation of many of the key changes that have occurred in the discipline throughout the history of modern surgery.

Key Words Incidental findings; best practices; quality improvement Abstract Purpose Actionable incidental findings (AIFs) are common in radiologic imaging. Imaging is commonly performed in emergency department (ED) visits, and AIFs are frequently encountered, but the ED presents unique challenges for communication and follow-up of these findings. The authors formed a multidisciplinary panel to seek consensus regarding best practices in the reporting, communication, and follow-up of AIFs on ED imaging tests. Methods A 15-member panel was formed, nominated by the ACR and American College of Emergency Physicians, to represent radiologists, emergency physicians, patients, and those involved in health care systems and quality. A modified Delphi process was used to identify areas of best practice and seek consensus. The panel identified four areas: (1) report elements and structure, (2) communication of findings with patients, (3) communication of findings with clinicians, and (4) follow-up and tracking systems. A survey was constructed to seek consensus and was anonymously administered in two rounds, with a priori agreement requiring at least 80% consensus. Discussion occurred after the first round, with readministration of questions where consensus was not initially achieved. Results Consensus was reached in the four areas identified. There was particularly strong consensus that AIFs represent a system-level issue, with need for approaches that do not depend on individual clinicians or patients to ensure communication and completion of recommended follow-up. Conclusions This multidisciplinary collaboration represents consensus results on best practices regarding the reporting and communication of AIFs in the ED setting.

Extraneous growth of scientific information over the Internet makes the searching task non-trivial and as a consequence researchers are facing difficulties in finding relevant papers from the millions of research papers in digital repositories. The research paper recommendation systems have been advocated to address this problem. The existing research paper recommendation systems lack in exploiting prominent information of papers, such as relevancy with the current time, novelty, scientific contribution, writing complexity of the papers, etc. Further, the existing models emphasize only on user's preference rather than user's intention that may change with time. Furthermore, the existing models do not consider a sound ranking strategy to unleash the personalization aspect and relevancy of papers. This work aims to address the existing limitations and proposes a systematic hidden attribute-based recommendation engine (SHARE). SHARE utilizes a feature engineering technique to unfold valuable insights of papers through multiple hidden features. These features are used as a context for users as well as multiple criteria for ranking papers. Additionally, SHARE predicts a user's intention beyond the user's preference to capture the dynamic notion of a user. Finally, a novel ranking strategy is proposed to retrieve personalized and the most important papers. SHARE is flexible for recommending both old and new users. In order to evaluate the effectiveness of SHARE both user studies and system evaluations were performed. Experimental results substantiate the efficacy of the proposed approach and are comparable to the existing systems. [ABSTRACT FROM AUTHOR]

Keywords IIoT; B2B; A-R-A model; System of Systems (SoS); Smart farming Highlights * Traditional representations of business networks may not be adapted in IIoT (Industrial Internet of Things) contexts. * In IIoT actors are not only humans or organizations. * In IIoT technologies are not necessarily resources. * A system of systems approach of business networks is introduced. * Impacts on new connections between actors, and value creation are discussed. Abstract In industrial business-to-business (B2B) markets, physical entities (such as products, machines, materials, or other objects) are increasingly connected among each other. This Industrial Internet of Things (IIoT) is quickly developing thanks to advances in fields such as information systems, factory digitalization, data sciences, robotics. Thus, industrial markets appear both as business networks - encompassing connections between individual or organizational actors -- and networks of connected things. The purpose of this research is to provide an integrative perspective that encompasses both types of networks. It seeks to contribute to the literature on industrial B2B markets in two ways. First, it proposes the system of systems (SoS) theory - which emphasizes diversity and autonomy of systems - as an integrative perspective. Second, it argues that this integrated perspective contributes to a new view on how resources are produced, combined, and used, and, therefore, on business network models. We discuss the implications for one of the most established models, the IMP Group's A-R-A model.

We nevertheless acknowledge that the B2B literature is increasingly adopting the term 'business ecosystem' (adapted to business context from biology by Moore (1993)). Often these terms are used interchangeably. This is our position in this paper (see also ; ). Sometimes differences are emphasized.

Paper-based flexible surface-enhanced Raman scattering (SERS) chips have been demonstrated to have great potential for future practical applications in point-of-care testing (POCT) due to the potentials of massive fabrication, low cost, efficient sample collection and short signal acquisition time. In this work, common filter paper and Ag@SiO 2 core-shell nanoparticles (NP) have been utilized to fabricate SERS chips based on shell‐isolated nanoparticle‐enhanced Raman spectroscopy (SHINERS). The SERS performance of the chips for POCT applications was systematically investigated. We used crystal violet as the model molecule to study the influence of the size of the Ag core and the thickness of the SiO 2 coating layer on the SERS activity and then the morphology optimized Ag@SiO 2 core-shell NPs was employed to detect thiram. By utilizing the smartphone as a miniaturized Raman spectral analyzer, high SERS sensitivity of thiram with a detection limit of 10−9M was obtained. The study on the stability of the SERS chips shows that a SiO 2 shell of 3 nm can effectively protect the as-prepared SERS chips against oxidation in ambient atmosphere without seriously weakening the SERS sensitivity. Our results indicated that the SERS chips by SHINERS had great potential of practical application, such as pesticide residues detection in POCT. [ABSTRACT FROM AUTHOR]

Keywords Metrics; Citations; Influence; Science; Status Highlights * More than half of citations to academic papers reflect little-to-no intellectual influence on the authors citing them. * Citations to already highly cited papers are 2--3 more likely to reflect substantial intellectual influence. * A key mechanism is citations change perceptions of quality: displaying low citation counts makes papers appear to be of lower quality. * Papers with poor perceived quality are read more superficially and discovered later in the projects. Abstract Although citations are widely used to measure the influence of scientific works, research shows that many citations serve rhetorical functions and reflect little-to-no influence on the citing authors. If highly cited papers disproportionately attract rhetorical citations then their citation counts may reflect rhetorical usefulness more than influence. Alternatively, researchers may perceive highly cited papers to be of higher quality and invest more effort into reading them, leading to disproportionately substantive citations. We test these arguments using data on 17,154 randomly sampled citations collected via surveys from 9,380 corresponding authors in 15 fields. We find that most citations (54%) had little-to-no influence on the citing authors. However, citations to the most highly cited papers were 2--3 times more likely to denote substantial influence. Experimental and correlational data show a key mechanism: displaying low citation counts lowers perceptions of a paper's quality, and papers with poor perceived quality are read more superficially. The results suggest that higher citation counts lead to more meaningful engagement from readers and, consequently, the most highly cited papers influence the research frontier much more than their raw citation counts imply.
