• 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.

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.

The underlying multi-stage integrated production process considers the following critical units: continuous digester, intermediate stocks of pulp and liquor, multiple paper machines and a recovery line to treat by-products. This work presents a mixed integer programming (MIP) model to represent the problem, as well as a solution approach based on a customized genetic algorithm (GA) with an embedded residual linear programming model. Some GA tools are explored, including literature and new operators, a novel diversification process and other features. In particular, the diversification process uses a new allele frequency measure to change between diversification and intensification procedures. Computational results show the effectiveness of the method to solve relatively large instances of the single paper machine problem when compared to other single paper machine solution methods found in the literature. For multiple paper machine settings, in most runs the GA solutions are better than those obtained for the MIP model using an optimization software.

• Flexible and disposable paper-based NO 2 sensor based on rGO/chitosan(CS) composite is proposed. • Synthesized rGO/CS composite can be easily deformed into various shapes because of its inherent characteristic. • The detection limit of NO 2 is 1 ppm and the possibility of application at the automobile exhaust is also confirmed. Nitrogen dioxide (NO 2) is a representative toxicant in air pollution that mostly arises from the exhaust gas released by automobiles. It is related to various respiratory diseases such as pneumonia and sudden infant death syndrome. Additionally, because the toxicity of nitrogen dioxide is high in overpopulated areas (i.e. , a capital or metropolis), the development of simple, practical, and facile sensors is highly needed. This work presents a flexible and disposable paper-based NO 2 sensor based on a reduced graphene oxide/chitosan (rGO/CS) composite. The synthesized rGO/CS composite can be easily flexed and deformed into various shapes, which are attributed to chitosan molecules that function as a dispersion and reduction agent and support material. In addition, this composite can be attached to paper owing to its adhesive property; hence it can be utilized in versatile applications in a disposable manner. By analyzing the conductive change of the rGO/CS composite when it reacts with NO 2 , we can detect nitrogen dioxide in a concentration range of 0–100 ppm with a detection limit of 1 ppm. Moreover, we performed NO 2 detection in the exhaust gas released by automobiles using the rGO/CS composite for practical application. The results indicated that the rGO/CS composite has the potential to be used in feasible gas sensing as a facile and disposable sensor under various conditions.

• A patterned paper-based energy storage device is fabricated by low-cost screen printing. • The device shows excellent energy storage, photothermal and electromagnetic shielding properties. • The whole paper device with good self-healing performance presents an ultra-high energy density. • White garbage can also be used to prepare high value-added energy storage material. Supercapacitors are favored by researchers because of their high power density, especially with the acceleration of people's life rhythm. However, their energy density, especially from the point of view of the whole energy storage device, is far lower than that of commercial batteries. In this work, a kind of customizable full paper-based supercapacitor device with excellent self-healing ability is fabricated by simple and low-cost screen printing, electropolymerization and dip coating methods. The resultant separator-free supercapacitor device exhibits both ultrahigh gravimetric and areal specific energy (power) densities of 39 Wh kg−1 (69 kW kg−1) and 692 μWh cm−2 (236 mW cm−2), achieving excellent supercapacitor performance. Notably, the addition of vitrimers endows the whole device with outstanding self-healing properties, which is helpful for enhancing the adaptability of the device to the environment. In addition, this kind of paper-based device also displays good photothermal and electromagnetic shielding performances. These striking features make paper matrix composites attractive in the fields of supercapacitors, medical photothermal treatment and electromagnetic shielding.

Keywords Academic publications; Firm value; Innovation; Patents; Human capital Highlights * Analyzes firm valuation effects of academic publications and patents of China's publicly listed firms. * Chinese firms' academic publications are positively associated with their market valuation. * This positive relation is more pronounced when these firms have stronger patent records. * Mechanism tests suggest Chinese firms' academic publications are beneficial to their human capital stock and function as credible signals of quality to the market. Abstract By combining various databases of academic publications and patents of China's publicly listed firms, we explore the effects of academic publications on firm valuation. We find that Chinese firms' academic publications are positively associated with their market valuation. More importantly, such a positive relation is more pronounced when these firms have stronger patent records, highlighting a synergy between basic research and applied technologies. Mechanism tests indicate that firms' academic publications promote their market values through enhancing their human capital and sending credible signals to the market. We also find that publications in English-language journals are more value-relevant than in Chinese-language journals.

Key Words Incidental; interstitial lung abnormalities; lung cysts; pulmonary nodule Abstract The ACR Incidental Findings Committee presents recommendations for managing incidentally detected lung findings on thoracic CT. The Chest Subcommittee is composed of thoracic radiologists who endorsed and developed the provided guidance. These recommendations represent a combination of current published evidence and expert opinion and were finalized by informal iterative consensus. The recommendations address commonly encountered incidental findings in the lungs and are not intended to be a comprehensive review of all pulmonary incidental findings. The goal is to improve the quality of care by providing guidance on management of incidentally detected thoracic findings.

Keywords Machine vision; Machine learning; Deep learning; State-of-the-art Highlights * Deep learning has brought about a revolution in machine vision. * Deep learning is changing the way machine vision is done. * Deep learning is opening new application markets for machine vision. Abstract Over the past few years, what might not unreasonably be described as a true revolution has taken place in the field of machine vision, radically altering the way many things had previously been done and offering new and exciting opportunities for those able to quickly embrace and master the new techniques. Rapid developments in machine learning, largely enabled by faster GPU-equipped computing hardware, has facilitated an explosion of machine vision applications into hitherto extremely challenging or, in many cases, previously impossible to automate industrial tasks. Together with developments towards an internet of things and the availability of big data, these form key components of what many consider to be the fourth industrial revolution. This transformation has dramatically improved the efficacy of some existing machine vision activities, such as in manufacturing (e.g. inspection for quality control and quality assurance), security (e.g. facial biometrics) and in medicine (e.g. detecting cancers), while in other cases has opened up completely new areas of use, such as in agriculture and construction (as well as in the existing domains of manufacturing and medicine). Here we will explore the history and nature of this change, what underlies it, what enables it, and the impact it has had - the latter by reviewing several recent indicative applications described in the research literature. We will also consider the continuing role that traditional or classical machine vision might still play. Finally, the key future challenges and developing opportunities in machine vision will also be discussed.

Keywords Literature review; Review papers; Scientometric; Scientific impact; Citation analysis Abstract Review papers are essential for knowledge development in Information Systems. While some are cited twice a day, others accumulate single digit citations over a decade. The magnitude of these differences prompts us to analyze what distinguishes those reviews that have proven to be integral to scientific progress from those that might be considered less impactful. Our results highlight differences between reviews aimed at describing, understanding, explaining, and theory testing. Beyond the control variables, they demonstrate the importance of methodological transparency and the development of research agendas. These insights inform all stakeholders involved in the development and publication of review papers.

Key Words Adnexal lesion; adnexal mass; MRI; ovarian mass; structured reporting Abstract MRI is used in the evaluation of ovarian and adnexal lesions. MRI can further characterize lesions seen on ultrasound to help decrease the number of false-positive lesions and avoid unnecessary surgery in benign lesions. Currently, the reporting of ovarian and adnexal findings on MRI is inconsistent because of the lack of standardized descriptor terminology. The development of uniform reporting descriptors can lead to improved interpretation agreement and communication between radiologists and referring physicians. The Ovarian-Adnexal Reporting and Data Systems MRI Committee was formed under the direction of the ACR to create a standardized lexicon for adnexal lesions with the goal of improving the quality and consistency of imaging reports. This white paper describes the consensus process in the creation of a standardized lexicon for ovarian and adnexal lesions for MRI and the resultant lexicon.

These recommendations represent an update from the liver component of the ACR 2010 white paper on managing incidental findings in the pancreas, adrenal glands, kidneys, and liver. The Liver Subcommittee -- which included five abdominal radiologists, one hepatologist, and one hepatobiliary surgeon -- developed this algorithm. The recommendations draw from published evidence and expert opinion and were finalized by informal iterative consensus. Algorithm branches categorize liver lesions on the basis of patient characteristics and imaging features. They terminate with an assessment of benignity or a specific follow-up recommendation. The algorithm addresses most, but not all, pathologies and clinical scenarios. The goal is to improve the quality of care by providing guidance on how to manage incidentally detected liver lesions.

These recommendations represent an update from the pancreatic component of the JACR 2010 white paper on managing incidental findings in the adrenal glands, kidneys, liver, and pancreas. The Pancreas Subcommittee -- which included abdominal radiologists, a gastroenterologist, and a pancreatic surgeon -- developed this algorithm. The recommendations draw from published evidence and expert opinion, and were finalized by informal iterative consensus. Algorithm branches successively categorize pancreatic cysts based on patient characteristics and imaging features. They terminate with an ascertainment of benignity and/or indolence (sufficient to discontinue follow-up), or a management recommendation. The algorithm addresses most, but not all, pathologies and clinical scenarios. Our goal is to improve quality of care by providing guidance on how to manage incidentally detected pancreatic cysts.

• A 3D lithophilic carbon paper/current collector integrated Li metal anode (Li@LCP-Cu) is prepared by hot-pressing method, which can precisely control the Li content and thickness. • The in-situ formed lithiophilic layer on the surface of CP can exist stably and reduce the nucleation overpotential, inducing uniform and dense Li deposition. • 3D CP skeleton can reduce local current density to suppress dendrite growth and limit anode volume change. • The solid-state battery assembled with Li@LCP-Cu, PVDF-based polymer electrolyte and PEO functional layer exhibits the best electrochemical and safety performance. Safety issues induced by infinite anode volume change and uncontrolled lithium (Li) dendrite growth have become the biggest obstacle to the practical application of Li metal batteries. In addition, the traditional rolling method makes it difficult to manufacture thin Li foil with high mechanical strength and low Li content. Herein, a three-dimensional (3D) lithophilic carbon paper/copper (Cu) current collector hybrid anode with ultra-low Li metal content is prepared by a hot-pressing method. The highly reversible and stable lithiophilic layer LiC x formed in situ by heating/pressing treatment provides abundant nucleation sites and reduces the Li nucleation overpotential, thereby effectively suppressing Li dendrite growth. Moreover, the volume change and pulverization problems of Li metal anode during deposition/stripping also can be accommodated by the 3D skeleton. The optimization effect has been directly confirmed by in-situ optical and ex-situ scanning electron microscope observation. Therefore, highly stable performance (158.4 mA h g−1 at 2 C after 200 cycles with a capacity retention of 95.24%) in Li@LCP-Cu||NCM811 coin cell can be achieved. Furthermore, the solid-state battery assembled with the hybrid anode, poly(vinylidene fluoride) (PVDF)-based polymer electrolyte and polyethylene oxide (PEO) interface functional layer also exhibits the best electrochemical and safety performance, which also proves that the Li@LCP-Cu anode has great potential for application in solid-state batteries.

This paper contrasts catch-up trends in CoPS with trends in mass-market commodity goods, such as those produced in South Korea. Developing countries are lagging behind in many CoPS areas and technological catch-up in CoPS industries is a very challenging process. This paper argues that due to specific technological and market regimes, the dominant model of technological catch-up in CoPS is based on path-following catch-up. Stage-skipping catch-up is only possible in minor technologies and path-creating catch-up is almost impossible in CoPS industry.

Purpose We sought to assess a smartphone-based, gold nanoparticle--based colorimetric lateral flow immunoassay paper sensor for quantifying urine 8-hydroxy-2'-deoxyguanosine (8-OHdG) as a biomarker for diabetic retinopathy (DR) screening. Methods Paper strips incorporate gold nanoparticle--8-OHdG antibody conjugates that produce color changes that are proportional to urine 8-OHdG and that are discernible on a smartphone camera photograph. Paper strip accuracy, precision, and stability studies were performed with 8-OHdG solutions of varying concentrations. Urine was collected from 97 patients with diabetes who were receiving DR screening examinations, including 7-field fundus photographs. DR was graded by standard methods as either low risk (no or mild DR) or high risk (moderate or severe DR). Paper sensor assays were performed on urine samples from patients and 8-OHdG values were correlated with DR grades. The differences in 8-OHdG values between the low- and high-risk groups were analyzed for outliers to identify the threshold 8-OHdG value that would minimize false-negative results. Results Lateral flow immunoassay paper strips quantitatively measure 8-OHdG and were found to be accurate, precise, and stable. Average urine 8-OHdG concentrations in study patients were 22 [plus or minus] 10 ng/mg of creatinine in the low-risk group and 55 [plus or minus] 11 ng/mg of creatinine in the high-risk group. Screening cutoff values of 8-OHdG >50 ng/mg of creatinine or urine creatinine >1.5 mg minimized screen failures, with 91% sensitivity and 81% specificity. Conclusions Urinary 8-OHdG is a useful biomarker to screen DR. Quantitative 8-OHdG detection with the lateral flow immunoassay paper sensor and smartphone camera demonstrates its potential in DR screening.

Purpose To assess time requirements for patient encounters and estimate after-hours demands of paper-based clinical workflows in ophthalmology. Design Time-and-motion study with a structured survey. Methods This study was conducted in a single academic ophthalmology department. A convenience sample consisted of 7 attending ophthalmologists from 6 subspecialties observed during 414 patient encounters for the time-motion analysis and 12 attending ophthalmologists for the survey. Outcome measurements consisted of total time spent by attending ophthalmologists per patient and time spent on documentation, examination, and talking with patients. The survey assessed time requirements of documentation-related activities performed outside of scheduled clinic hours. Results Among the 7 attending ophthalmologists observed (6 men and 1 woman), mean [plus or minus] SD age 43.9 [plus or minus] 7.1 years, during encounters with 414 patients (57.8 [plus or minus] 24.6 years of age), total time spent per patient was 8.1 [plus or minus] 4.8 minutes, with 2.8 [plus or minus] 1.4 minutes (38%) for documentation, 1.2 [plus or minus] 0.9 minutes (17%) for examination, and 3.3 [plus or minus] 3.1 minutes (37%) for talking with patients. New patient evaluations required significantly more time than routine follow-up visits and postoperative visits. Higher clinical volumes were associated with less time per patient. Survey results indicated that paper-based documentation was associated with minimal after-hours work on weeknights and weekends. Conclusions Paper-based documentation takes up a substantial portion of the total time spent for patient care in outpatient ophthalmology clinics but is associated with minimal after-hours work. Understanding paper-based clinical workflows may help inform targeted strategies for improving electronic health record use in ophthalmology.

Key Words Adnexal cyst; CT; incidental findings; MRI; ovarian cyst Abstract The ACR Incidental Findings Committee (IFC) presents recommendations for managing adnexal masses incidentally detected on CT and MRI. These recommendations represent an update of those provided in our previous JACR 2013 white paper. The Adnexal Subcommittee, which included six radiologists with subspecialty expertise in abdominal imaging or ultrasound and one gynecologist, developed this algorithm. The recommendations draw from published evidence and expert opinion and were finalized by iterative consensus. Algorithm branches successively categorize adnexal masses based on patient characteristics (eg, pre- versus postmenopausal) and imaging features. They terminate with a management recommendation. The algorithm addresses most, but not all, pathologies and clinical scenarios. Our goal is to improve quality of care by providing guidance on how to manage incidentally detected adnexal masses.

Langer (k), Carl C. Reading (l), Leslie M. Scoutt (m), A. Thomas Stavros (n) Abstract: Thyroid nodules are a frequent finding on neck sonography. Most nodules are benign; therefore, many nodules are biopsied to identify the small number that are malignant or require surgery for a definitive diagnosis. Since 2009, many professional societies and investigators have proposed ultrasound-based risk stratification systems to identify nodules that warrant biopsy or sonographic follow-up. Because some of these systems were founded on the BI-RADS.sup.[R] classification that is widely used in breast imaging, their authors chose to apply the acronym TI-RADS, for Thyroid Imaging, Reporting and Data System. In 2012, the ACR convened committees to (1) provide recommendations for reporting incidental thyroid nodules, (2) develop a set of standard terms (lexicon) for ultrasound reporting, and (3) propose a TI-RADS on the basis of the lexicon. The committees published the results of the first two efforts in 2015. In this article, the authors present the ACR TI-RADS Committee's recommendations, which provide guidance regarding management of thyroid nodules on the basis of their ultrasound appearance. The authors also describe the committee's future directions.

Key Words Corporate radiology; diagnostic imaging; health care finance; radiology Abstract Consolidation in health care has been widely recognized as having significant impact in the United States. A related trend is the corporatization of medical professional practices by companies in capital markets. Several medical subspecialties have been identified as attractive corporatization candidates, including radiology. The purpose of the white paper is to present information about the trend of corporatization in radiology. The real, recognized, and potential influences of capital investors in radiology need to be acknowledged as evolving and important considerations. Many radiologists and practices have already realized significant change as a result of corporatization. Corporatization presents significant practical, financial, ethical, and moral implications for those in and related to radiology.

Currently, text documents from multiple sources have become available in many fields. It is of great interest to study the relationship between documents from different sources and uncover the underlying causality. Zhu et al. (2021) proposed a joint dynamic topic model (JDTM). They classified all topics into three groups and used the "shared topics" with a fixed time lag order to characterize the shared information between two corpora. Although JDTM is a powerful tool for discovering the lead-lag relationship, there are two potential shortcomings. First, different shared topics should have distinct meanings, which should lead to different time lag orders between the two corpora. Second, for dynamic documents, not all topics are represented in each time slice, and thus topic sparsity should be considered. To address these two problems, we propose a sparse joint dynamic topic model (SJDTM) with a flexible lead-lag order. We assume a birth-and-death mechanism for all topics and a flexible lead-lag order for different shared topics. The performance of SJDTM is evaluated using both synthetic data and two real text corpora consisting of conference papers and journal papers. [ABSTRACT FROM AUTHOR]
