Published: January 2024

AbstractThe consumption of coal in winter heating period in northern China is large, and the combustion generates greenhouse gases that pollute the environment. At the same time, wind abandonment is widespread in northern China, causing waste of energy. In order to solve these problems, this paper proposes to apply clean energy heating and waste wind power generation for heating, and build a multi‐objective optimal dispatching model under the goal of considering customer satisfaction and operating costs. Finally, taking a region in the north of China as an example, the improved genetic algorithm is used to solve the model, the improved genetic algorithm ensures the survival rate of excellent genes, which is more efficient than the traditional genetic algorithm. The example results verify that the use of clean energy heating can increase the wind power consumption space and reduce the heating cost in winter.

Context. The soft X-ray instrument eROSITA on board the Spectrum-Roentgen-Gamma (SRG) observatory has successfully completed four of the eight planned all-sky surveys, detecting almost one million X-ray sources during the first survey (eRASS1). The catalog of this survey will be released as part of the first eROSITA data release (DR1).
Aims. Based on X-ray aperture photometry, we provide flux upper limits for eRASS1 in several energy bands. We cover galactic longitudes between 180° ≲ l ≲ 360° (eROSITA-DE). These data are crucial for studying the X-ray properties of variable and transient objects, as well as non-detected sources in the eROSITA all-sky survey data.
Methods. We performed aperture photometry on every pixel of the SRG/eROSITA standard pipeline data products for all available sky tiles in the single detection band (0.2–2.3 keV). Simultaneously, we performed the same analysis in the three-band detection at soft (0.2–0.6 keV), medium (0.6–2.3 keV), and hard (2.3–5.0 keV) energy bands. Based on the combination of products for the individual bands, we are also able to provide aperture photometry products and flux upper limits for the 0.2–5.0 keV energy band. The upper limits were calculated based on a Bayesian approach that utilizes detected counts and background within the circular aperture.
Results. The final data products consist of tables with the aperture photometry products (detected counts, background counts, and exposure time), a close-neighbor flag, and the upper flux limit based on an absorbed power-law spectral model (Γ = 2.0, NH = 3 × 1020 cm−2). The upper limits are calculated using the one-sided 3σ confidence interval (CL) of a normal distribution, representing CL = 99.87%. The aperture photometry products allow for an easy computation of upper limits at any other confidence interval and spectral model. These data are stored in a database with hierarchical indexes in order to offer a fast query option.
Conclusions. We provide a detailed description of the process of retrieving SRG/eROSITA upper limits for a large set of input positions, as well as of the eROSITA data, the X-ray aperture photometry, the upper limit calculation, and the final data products. The eROSITA upper flux limits represent either the maximum flux of potential non-detections or the 3σ upper flux uncertainty of detected sources. We emphasize the importance of choosing the right spectral model that ought to match the spectral shape of the source of interest: the wrong spectral model can produce discrepancies of up to 30% in the final flux upper limit value. We also describe the architecture of the database and the web tool, which are designed to handle large queries on input positions.

Published: January 2024

Purpose The aim of this study was to develop an algorithm to automatically extract annotations from German thoracic radiology reports to train deep learning-based chest X-ray classification models.
Materials and Methods An automatic label extraction model for German thoracic radiology reports was designed based on the CheXpert architecture. The algorithm can extract labels for twelve common chest pathologies, the presence of support devices, and “no finding”. For iterative improvements and to generate a ground truth, a web-based multi-reader annotation interface was created. With the proposed annotation interface, a radiologist annotated 1086 retrospectively collected radiology reports from 2020–2021 (data set 1). The effect of automatically extracted labels on chest radiograph classification performance was evaluated on an additional, in-house pneumothorax data set (data set 2), containing 6434 chest radiographs with corresponding reports, by comparing a DenseNet-121 model trained on extracted labels from the associated reports, image-based pneumothorax labels, and publicly available data, respectively.
Results Comparing automated to manual labeling on data set 1: “mention extraction” class-wise F1 scores ranged from 0.8 to 0.995, the “negation detection” F1 scores from 0.624 to 0.981, and F1 scores for “uncertainty detection” from 0.353 to 0.725. Extracted pneumothorax labels on data set 2 had a sensitivity of 0.997 [95 % CI: 0.994, 0.999] and specificity of 0.991 [95 % CI: 0.988, 0.994]. The model trained on publicly available data achieved an area under the receiver operating curve (AUC) for pneumothorax classification of 0.728 [95 % CI: 0.694, 0.760], while the models trained on automatically extracted labels and on manual annotations achieved values of 0.858 [95 % CI: 0.832, 0.882] and 0.934 [95 % CI: 0.918, 0.949], respectively.
Conclusion Automatic label extraction from German thoracic radiology reports is a promising substitute for manual labeling. By reducing the time required for data annotation, larger training data sets can be created, resulting in improved overall modeling performance. Our results demonstrated that a pneumothorax classifier trained on automatically extracted labels strongly outperformed the model trained on publicly available data, without the need for additional annotation time and performed competitively compared to manually labeled data.

Authors: Ayala Nina K. , Fain Audra C. , Smith Megan M. , Schlichting Lauren E. , Hamel Maureen S. , Werner Erika F. 
Published: January 2024

Objective We aimed to evaluate uptake of the glucose tolerance test performed during delivery hospitalization as part of routine clinical care.
Study Design This is a retrospective cohort study of people with GDM at a tertiary center. We collected 9 months of postimplementation data after the in-hospital (“early”) glucose tolerance test was adopted as a routine screening option. Adherence was compared between those who elected early glucose tolerance testing versus those who deferred testing to the standard postpartum period. Bivariable statistics including demographics, care team, and postpartum testing/visit attendance were compared between those who received early testing and those who did not using chi-square, Fisher's exact, and t-tests.
Results A total of 681 patients with GDM delivered during the study period. Of those who had an early glucose tolerance test ordered (n = 408), 340 (83.3%) completed the test. Among those who did not complete an early glucose tolerance test (ordered and not completed or never ordered), only 104/341 (30.5%) completed any postpartum glucose testing in the first 12 months of postpartum. There were significant differences in characteristics in terms of race/ethnicity, insurance, type of gestational diabetes (A1GDM vs. A2GDM), diabetes medications, obstetric care provider, and delivery mode. Among those who completed early testing, 43.7% of participants had impaired glucose metabolism and 6.5% had values concerning for overt diabetes mellitus. Among those who deferred testing to the standard 6- to 12-week period, 24.0% had impaired glucose metabolism and none had overt diabetes. Those who completed an early glucose tolerance test had a lower rate of postpartum visit attendance compared with those who deferred (75.6 vs. 91.5%, p < 0.01).
Conclusion In this cohort, when the early glucose tolerance test is offered in clinical practice, adherence rates are higher than when the test is deferred until the postpartum visit.

Published: January 2024

Abstract
Background Surgical incisional approach to the ascending aorta is the main strategic step during valvular and/or subvalvular aortic interventions. Classic aortotomy incisions (transverse or oblique) can be challenging and can cause suboptimal exposure of the aortic root especially for the patients with small aortic annulus or for redo coronary artery bypass patients with patent proximal grafts interposed to the ascending aorta.
Methods The Kırali incision was used in 91 patients (including 13 reoperations) who underwent an aortic intervention for valvular and subvalvular pathologies. Aortic root was exposed by forming inverted “U” shape incision starting from approximately 3 cm above the right coronary ostium toward the center of the noncoronary annulus and the top of the left–right commissure like a tongue.
Results The aortic valve was replaced with a mechanical prosthesis in 45 patients and with a bioprosthesis in 39 patients including 14 sutureless and 16 stentless prostheses. A total of 29 patients received a concomitant procedure per the following: coronary artery bypass grafting on 8 patients and left ventricular assist device on 7 patients. There was no any problem related to aortotomy incision technique such as bleeding, rupture, dehiscence, or laceration perioperatively. There was no complication related to the procedure during 5-year follow-up.
Conclusion This new aortotomy incision technique is a safe procedure that provides good exposure for all kinds of aortic valve interventions and protects grafts and can facilitate aortic root enlargement or aortoplasty easily. This incision has the potential to be an alternative to traditional techniques.
A Small Ratio of Proximal to Distal Bone Fragments Is a Risk Factor for Scaphoid Nonunion: A Volumetric Analysis of Preoperative CT
Authors: Sugiura Hirotaka , Tatebe Masahiro , Yoneda Hidemasa , Nishizuka Takanobu , Morita Akimasa , Yamamoto Michiro 
Published: January 2024

Abstract
Background Small proximal bone fragments are a known risk factor for nonunion, but it is not known what ratio of proximal to distal bone fragments actually results in nonunion.
Objective We hypothesized that a small proximal ratio of proximal scaphoid fragment volume to distal scaphoid volume as measured by preoperative computed tomography (CT) would be a risk factor for postoperative scaphoid nonunion.
Patients and Methods We retrospectively examined the factors that led to postoperative nonunion in 78 patients who underwent surgery using free bone grafts for scaphoid nonunion. Nonunion was defined as no evidence of union on plain radiography or CT more than 3 months after injury. Three-dimensional models of scaphoid fractures were created from the preoperative CT of all cases, and volumes were measured. Other patient characteristics, surgical methods, and imaging were investigated.
Results Persistent nonunion was observed in 13 patients after surgery, a rate of 16.7%. A multivariate analysis showed that only the proximal fragment ratio was an independent factor (union group 0.94, persistent nonunion group 0.54, p = 0.03). Receiver operating characteristic analysis showed that a proximal fragment ratio less than 0.66 was associated with persistent nonunion.
Conclusion Treatment of scaphoid nonunion with a small proximal fragment ratio should be based on a thorough understanding of the anatomy, blood flow, and carpal kinematics of the scaphoid bone itself.

Abstract
Background The role of dual-modality drainage of walled-off necrosis (WON) in patients with acute pancreatitis (AP) is established. However, there are no data on the association of clinical outcomes with the timing of percutaneous catheter drainage (PCD). We investigated the impact of the timing of PCD following endoscopic drainage of WON on clinical outcomes in AP.
Materials and Methods This retrospective study comprised consecutive patients with necrotizing AP who underwent endoscopic cystogastrostomy (CG) of WON followed by PCD between September 2018 and March 2023. Based on endoscopic CG to PCD interval, patients were divided into groups (≤ and >3 days, ≤ and >1 week, ≤ and >10 days, and ≤ and >2 weeks). Baseline characteristics and indications of CG and PCD were recorded. Clinical outcomes were compared between the groups, including length of hospitalization, length of intensive care unit stay, need for surgical necrosectomy, and death during hospitalization.
Results Thirty patients (mean age ± standard deviation, 35.5 ± 12.7 years) were evaluated. The mean CG to PCD interval was 11.2 ± 7.5 days. There were no significant differences in baseline characteristics and indications of CG and PCD between the groups. The mean pain to CG interval was not significantly different between the groups. Endoscopic necrosectomy was performed in a significantly greater proportion of patients undergoing CG after 10 days (p = 0.003) and after 2 weeks (p = 0.032). There were no significant differences in the complications and clinical outcomes between the groups.
Conclusion The timing of PCD following endoscopic CG does not affect clinical outcomes.
The Role of Proximal Locking Fixation in Volar Distal Radius Fracture Fixation
Authors: Gossett Leland , Vu Giap H. , Reizner Wayne , Gira Emma , Qiu Bowen , Awad Hani A. , Ketonis Constantinos 
Published: January 2024

Abstract
Background Volar-locked plating has become a popular treatment option for unstable distal radius fractures. While using locking screws in the distal fragment increases the stability of the fixation, the biomechanical benefits of locking fixation in the proximal fragment have not been definitively established.
Purposes This study evaluated the initial mechanical behavior of the volar plating construct with different locking screw configurations in the proximal fragment.
Methods Sixteen Sawbones radius models were used. An unstable metaphyseal distal radius fracture was created and fixated with a volar-locked plate. Four different screw configurations in the proximal fragment were tested: all nonlocking screws, locking screw in the distal-most hole, locking screw in the proximal-most hole, and locking screws in both the proximal- and distal-most holes. Initial stiffness, displacement during harmonic loading, and load-to-failure were compared among the three groups.
Results The initial stiffness, displacement during harmonic loading, and load-to-failure did not significantly differ among the four proximal screw configurations (p < 0.05). Failure occurred via toggling of the screws in the configuration with all nonlocking screws and through screw breakage or locking mechanism failure in the configurations with locking screws.
Conclusions The use of locking screws in the proximal fragment did not significantly affect the initial stability of volar distal radius plating. However, failure modes differed between the nonlocking and locking configurations, consistent with known mechanical properties of locking fixation. Further mechanical studies in cadaveric models and clinical trials are warranted to determine the optimal screw configuration in volar distal radius plating.
Level of Evidence To be determined. Biomechanical study on synthetic models.

Published: January 2024

Abstract
Background Hemiarthroplasty may be indicated for patients with distal radioulnar joint (DRUJ) arthritis. Recently, the use of the pyrocarbon metacarpophalangeal implant has been proposed as a novel means of treating DRUJ arthritis due to the materials improved mechanical properties and wear characteristics.
Purpose and Questions This study compares midterm outcomes of metallic and pyrocarbon hemiarthroplasties for the treatment of symptomatic DRUJ arthritis. Questions of interest included outcomes and complications.
Patients and Methods In total, 32 hemiarthroplasties, 10 metallic and 22 pyrocarbon, were performed between 2010 and 2020 by three surgeons at one tertiary medical center. Patients' retrospective outcomes were extracted from the electronic medical record.
Results Postoperatively, the metallic implant group (mean follow-up: 38 months) demonstrated decreased pain but no changes in range of motion. Comparatively, the pyrocarbon group experienced an improved range of motion and postoperative pain (p < 0.05). Radiographic analysis demonstrated 10% of metallic implants and 9% of pyrocarbon implants to have resulted in thinning of the lateral cortex of the radius at the final follow-up. Minor complications in metallic and pyrocarbon implant groups warranting reoperation occurred at rates of 10 and 13.5% while implant failure occurred at a rate of 30 and 18%, respectively.
Discussion Within this study, pyrocarbon implants resulted in significant functional improvement with comparable complication and failure rates to the metallic implant. Long-term stability demonstrated efficacy for both techniques in symptomatic DRUJ treatment.

Social capital development on interest-based networks: examining its antecedents, process, and consequences
Authors: Chen Meng , Li Wu 
Published: January 2024

AbstractSocial capital development has been extensively studied on relationship-based networks (i.e., Facebook, WeChat), whereas scant attention has been devoted to another critical category: interest-based networks. People join interest-based networks primarily to exchange information on shared topics and interests, as opposed to relationship development or maintenance. Guided by social capital theory, the current research takes an initial step by looking into whether and how bridging and bonding social capital accrues on interest-based networks. A cross-sectional survey was conducted among users of a well-known Chinese interest-based network, Douban.com (N = 624). The participants reported their bridging and bonding social capital, frequency of online interactions with content (i.e., posting, favoriting) and with humans (i.e., chatting, discussing), and sense of belonging. The mediation analysis results informed us of a theoretical model of social capital development on interest-based networks with both online interactions with content and with humans as the antecedents, and a sense of belonging as the consequence. The findings also revealed the steps of bridging and bonding social capital development on interest-based networks. This study advanced our understanding of social capital theory by examining its applicability in an interest-based SNS, identifying OIs with humans and content as potential antecedents, and elucidating the association between two types of social capital. The findings hold practical significance for designers of interest-based networks.
Computational philosophy: reflections on the PolyGraphs project
Authors: Ball Brian , Koliousis Alexandros , Mohanan Amil , Peacey Mike 
Published: January 2024

AbstractIn this paper, we situate our computational approach to philosophy relative to other digital humanities and computational social science practices, based on reflections stemming from our research on the PolyGraphs project in social epistemology. We begin by describing PolyGraphs. An interdisciplinary project funded by the Academies (BA, RS, and RAEng) and the Leverhulme Trust, it uses philosophical simulations (Mayo-Wilson and Zollman, 2021) to study how ignorance prevails in networks of inquiring rational agents. We deploy models developed in economics (Bala and Goyal, 1998), and refined in philosophy (O’Connor and Weatherall, 2018; Zollman, 2007), to simulate communities of agents engaged in inquiry, who generate evidence relevant to the topic of their investigation and share it with their neighbors, updating their beliefs on the evidence available to them. We report some novel results surrounding the prevalence of ignorance in such networks. In the second part of the paper, we compare our own to other related academic practices. We begin by noting that, in digital humanities projects of certain types, the computational component does not appear to directly support the humanities research itself; rather, the digital and the humanities are simply grafted together, not fully intertwined and integrated. PolyGraphs is notably different: the computational work directly supports the investigation of the primary research questions, which themselves belong decidedly within the humanities in general, and philosophy in particular. This suggests an affinity with certain projects in the computational social sciences. But despite these real similarities, there are differences once again: the computational philosophy we practice aims not so much at description and prediction as at answering the normative and interpretive questions that are distinctive of humanities research.
Lifelong learning in the workplace: the knowledge management role of corporate universities in China
Authors: Han Yuhang , Zhou Yi , Carr Sarah , Jiang Jiaoyan 
Published: January 2024

AbstractIn the current era of constant change, both employees and enterprises face the daunting challenge of lifelong learning. To address enterprises’ dissatisfaction with the knowledge provided by traditional universities, a growing number of corporate universities are being established, representing a crucial strategic pathway for enterprises. This study thus adopts the coding methodology of grounded theory to analyze the internal mechanism of a sample of seven corporate universities in China enabling organizations’ lifelong learning. Adopting the knowledge-based view (KBV), this study also identifies how corporate universities empower organizations, establishing a path model whose paths include “generating strategic knowledge”, “sharing business knowledge”, “optimizing governance knowledge” and “transforming cultural knowledge”. Accordingly, this study establishes a theoretical path model and explores how to empower organizations’ lifelong learning in the context of China. Moreover, our qualitative conclusions not only enrich the literature on corporate universities and their complex functions concerning lifelong learning and knowledge management but also have important implications for managers in enterprises and corporate universities.
