Published: November 2023

AbstractLumbar hernia is a rare lateral abdominal wall hernia. Various surgical repair strategies have been recorded, but there is currently no unified standard. A Chinese surgeon recently revealed a novel technique for treating primary lumbar hernia called retroperitoneal totally endoscopic prosthetic repair (R-TEP). We have made a further exploration of this method and successfully used it in the treatment of secondary lumbar hernia. We successfully performed R-TEP on three patients with lumbar hernias. All patients were female with an average age of 64 years (51–71 years). Two patients each had a primary upper lumbar hernia, while one patient had a secondary lumbar hernia. With a mean operative time of 77 min (60–105 min), all operations were performed successfully. The average visual analogue scale (VAS) was 1.3 points (1–2 points) on the second day following surgery. The mean postoperative hospital stay was 2.3 days (2–3 days). No postoperative complications occurred. During a mean follow-up period of 19 months (10–24 months), there was no recurrence of the hernia, chronic pain or mesh infection. Therefore, R-TEP is safe and effective for both primary and secondary lumbar hernia. Anti-adhesive coated meshes are not required, making this a cost-effective procedure that is worthy of recommendation.

AbstractExcessive proliferation of filamentous bacteria within activated sludge leads to sludge structural instability and diminished settling properties, which is a prevalent issue in tannery wastewater treatment. Based on available information, there is a lack of research on the impact of particle addition on filamentous bacteria in activated sludge, specifically with respect to a reduction in sludge bulking. Therefore, polyethylene terephthalate (PET) was selected as the test material to elucidate the effect of particles on sludge bulking. The results illustrate that particles measuring 0.1 mm in diameter have a profound influence on both the quantity and morphological characteristics of filamentous bacteria in activated sludge. In an anaerobic-aoxic-oxic (AAO) reactor, the use of 4000 particles/L led to a significant decrease in the sludge volume index (SVI), reducing it from 358 mg/L to 198 mg/L. The results offer significant insights for resolving sludge bulking problems in tannery wastewaters. Moreover, the results are significant as a reference point for future investigations on the efficacy of incorporating diverse particulate materials to ameliorate issues associated with activated sludge bulking.

AbstractMicrobial fuel cells (MFCs) are a self-sustaining and environmentally friendly system for the simultaneous was tewater treatment and bioelectricity generation. The type and material of the electrode are critical factors that can influence the efficiency of this treatment process. In this study, graphite plates and carbon felt were modified through the electrodeposition of nickel followed by the formation of a biofilm, resulting in conductive bio-anode thin film electrodes with enhanced power generation capacity. The structural and morphological properties of the electrode surfaces were characterized using X-ray diffraction, energy-dispersive X-ray spectroscopy, elemental mapping, and field-emission scanning electron microscopy techniques. Maximum voltage, current density, and power generation were investigated using a dual-chamber MFC equipped with a Nafion 117 membrane and bio-nickel-doped carbon felt (bio-Ni@CF) and bio-nickel-doped graphite plate (bio-Ni@GP) electrodes under constant temperature conditions. The polarization and power curves obtained using different anode electrodes revealed that the maximum voltage, power and current density achieved with the bio-Ni@CF electrode were 468.0 mV, 130.72 mW/m2 and 760.0 mA/m2 respectively. Moreover, the modified electrodes demonstrated appropriate stability and resistance during successful runs. These results suggest that nickel-doped carbon-based electrodes can serve as suitable and stable supported catalysts and conductors for improving efficiency and increasing power generation in MFCs.
Network representations of attractors for change point detection

Published: November 2023

AbstractA common approach to monitoring the status of physical and biological systems is through the regular measurement of various system parameters. Changes in a system’s underlying dynamics manifest as changes in the behaviour of the observed time series. For example, the transition from healthy cardiac activity to ventricular fibrillation results in erratic dynamics in measured electrocardiogram (ECG) signals. Identifying these transitions—change point detection—can be valuable in preparing responses to mitigate the effects of undesirable system changes. Here, we present a data-driven method of detecting change points using a phase space approach. Delay embedded trajectories are used to construct an ‘attractor network’, a discrete Markov-chain representation of the system’s attractor. Once constructed, the attractor network is used to assess the level of surprise of future observations where unusual movements in phase space are assigned high surprise scores. Persistent high surprise scores indicate deviations from the attractor and are used to infer change points. Using our approach, we find that the attractor network is effective in automatically detecting the onset of ventricular fibrillation (VF) from observed ECG data. We also test the flexibility of our method on artificial data sets and demonstrate its ability to distinguish between normal and surrogate time series.

Published: November 2023

AbstractAlthough the potential for cities and regions to contribute to global mitigation efforts is widely acknowledged, there is little evidence on the effectiveness of subnational mitigation strategies. Here we address this gap through a systematic review of 234 quantitative mitigation case studies. We use a meta-analytical approach to estimate expected greenhouse gas emissions reductions from 12 categories of mitigation strategies. We find that strategies related to land use and development, circular economy, and waste management are most effective and reliable for reducing emissions. The results demonstrate that cities and regions are taking widespread action to reduce emissions. However, we find misalignment between the strategies that policymakers and researchers focus on, compared to those with the highest expected impacts. The results inform climate action planning at the city and regional level and the evaluation of subnational climate targets.
Design of fuzzy sliding mode controller for islanded AC/DC hybrid microgrid with cyber‐attacks
Authors: Jiang He , Zhao Yan , Su Hanguang , Wang Yuzhong 
Published: November 2023

AbstractThis paper presents a fuzzy sliding mode control method for voltage control of islanded AC/DC hybrid microgrid. The T‐S fuzzy model is utilized to approximate initial non‐linear dynamic model of the microgrid. The fuzzy rules and membership functions are designed according to the coupling relationship between AC part and DC part. To reduce the influence of external disturbance and cyber‐attacks, an integral sliding mode controller is considered. Furthermore, a sufficient condition is proposed with attenuation performance to ensure the asymptotic stability of sliding motion. The set of gain matrices can be acquired via solving the linear matrix inequalities deduced from the Lyapunov stability analysis. The reachability to the proposed sliding mode surface can be guaranteed via switching control law based on a Lyapunov function. In addition, to eliminate chattering performance of the sliding mode control theory, the fuzzy logic controller is designed to optimize the switching region in boundary layers of saturation functions. Finally, the simulation results for the islanded AC/DC hybrid microgrid are implemented to verify the robustness and effectiveness of the designed fuzzy sliding mode control method.

Published: November 2023

AbstractIn the current complex situations of electronic intelligence (ELINT), the authors present a radar emitter structure (RES) identification method based on deep learning at a new level to address the issue of incomplete cognitive information. Firstly, due to the fact that existing simulation data cannot fully reflect the structure features of the entire radar emitter, the structure feature‐level RES model is built using direct digital synthesiser (DDS) technology and radio frequency (RF) simulation platform. Afterwards, considering that the structure features are reflected in the frequency domain, a stacked frequency sparse auto encoder (sFSAE) network is constructed by adding a constraint term in frequency domain to the loss function of sparse auto encoder (SAE). Using deep learning to extract structure features with constraints in different domains is instructive for feature extraction techniques under variable operating parameters. Finally, the extracted structure features are input into the Softmax classifier to perform the identification from the radar signal to the RES. The experimental results show that the proposed method has high generalisation ability and robustness under different modulation types, different operating parameters and different signal to noise ratio (SNR). It also has a high identification rate even for untrained modulated signals.

Published: November 2023

Objective To evaluate the relationship between intrahepatic cholestasis of pregnancy (ICP) and coronavirus disease 2019 (COVID-19).
Study Design We performed a retrospective cohort study of pregnant women undergoing induction of labor (IOL) at a single institution between May 2020 to January 2021. Primary exposure was diagnosis of intrahepatic cholestasis of pregnancy (ICP). The primary outcome was the prevalence of COVID-19 as determined by reverse-transcriptase polymerase chain reaction testing on nasopharyngeal swabs for SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) on routine admission testing. Secondary outcomes were abnormal laboratory values and adverse fetal outcomes. Logistic regression with log link analysis was performed comparing patients undergoing IOL for ICP compared with IOL for all other indications. The moderating effect of ethnicity was assessed by the interaction between ethnicity and ICP in a logistic regression model. The Wilcoxon rank-sum test and Fisher's exact test were performed for the secondary outcome analyses.
Results Over the course of the study, 596 patients underwent IOL: 24 for ICP and 572 for other indications. The overall prevalence of COVID-19 positivity in the cohort was 5.5% (33 of 596). Those with ICP were more likely to test positive for COVID-19 compared with those with other IOL indications (29.2 vs. 4.5%, RR = 6.4, 95% CI: 2.8–12.5, p < 0.001). All patients with ICP who tested positive for COVID-19 were Hispanic. To analyze the moderating effect of ethnicity, the results of the logistic model found the interaction between ethnicity and ICP to not be significant (p = 0.991). In patients with ICP, the median AST (aspartate aminotransferase) was higher than those with COVID-19 (p = 0.0182). There were no adverse fetal outcomes in the ICP group.
Conclusion In this single-site retrospective cohort study, we demonstrated an increased prevalence of COVID-19 in those with ICP in general and among Hispanic patients specifically. Despite this difference, there was no increased risk of adverse fetal outcomes.

Published: November 2023

Objective To evaluate whether use of both preoperative 2% chlorhexidine gluconate abdominal cloth and 4% chlorhexidine gluconate vaginal scrub is effective in reducing surgical site infections (SSIs) in patients undergoing cesarean delivery after labor.
Study Design This is a single-center, randomized clinical trial in which patients were randomized 1:1 to receive 2% chlorhexidine gluconate cloth applied to the abdomen in addition to the application of 4% chlorhexidine gluconate vaginal scrub versus standard of care. The primary outcome was rate of SSIs, including endometritis, by 6 weeks postdelivery. The secondary outcomes were other wound complications (erythema at the operative site, skin separation, drainage, fever, hematoma, seroma) by 6 weeks postdelivery, hospital readmission for wound complications, and day of discharge after cesarean delivery.
Results A total of 319 patients between September 2018 and February 2021 met eligibility criteria: 160 were randomized to the chlorhexidine gluconate abdominal cloth and vaginal scrub group and 159 were randomized to the standard of care group. The groups did not have significant differences in maternal demographic characteristics. Of the 302 (95%) individuals included in primary analysis, there was no statistically significant difference in SSI and endometritis rate by 6 weeks postdelivery (6.6% in chlorhexidine vs. 5.3% standard of care, p = 0.65). Secondary outcomes were also similar among the two groups.
Conclusion The combination of preoperative 2% chlorhexidine gluconate abdominal cloth and 4% chlorhexidine gluconate vaginal scrub does not appear to reduce the risk of SSI with cesarean delivery after trial of labor when compared with standard of care.

The Molecular Structure of Fibrinogen
Authors: Murano Genesio 
Published: November 2023

Abstract
Seminars in Thrombosis and Hemostasis (STH) celebrates 50 years of publishing in 2024. To celebrate this landmark event, STH is republishing some archival material. This manuscript represents the first full paper ever published in STH. The manuscript published without an abstract, and essentially covered in considerable detail the molecular structure of fibrinogen, as was known at that time. Fittingly, it covers some historical perspectives, the physicochemical properties and structure of fibrinogen across several species of animals (including humans) and its transformation into fibrin. We hope the readers of STH enjoy this journey into the past. This manuscript is accompanied by a Commentary that reflects on this past, as well as the journey towards contemporary understanding of the molecular structure of fibrinogen. As this is a republication of archival material, transformed into a modern format, we apologise in advance for any errors introduced during this transformation.

Published: November 2023

Abstract
Background Acute facial trauma in motor vehicle accident defects may be associated with skeletal, neuromuscular, or mucosal losses. Simultaneous repair of the critical structures in these defects mandates the use of flap cover; paucity of local tissues necessitates the use of free skin flaps.
Materials and Methods Six free flap reconstructions for acute facial trauma defects over a 10-year period were reviewed. The defect location, associated injuries, flap choice, additional reconstructive procedures, and flap outcomes were analyzed.
Results There were four males and two females with ages between 18 and 63 years. Four defects were located in the lateral face and scalp, and two in the lower central face. Defect size ranged between 96 and 346 cm2. There were fractures in three, facial nerve injuries in two, and loss of facial muscles in one. Five free flaps were anterolateral thigh flap; simple and composite, one was a radial artery forearm flap. Recipient pedicles were the superficial temporal vessels in two and facial vessels in four cases. There were no re-explorations but one flap necrosed on 7th postoperative day on account of invasive aspergillosis.
Discussion Use of free flaps for ballistic wounds is common. In uncommon nonballistic traumatic facial defects, the location, nature of the defect, and type of associated injuries and need for simultaneous reconstructions may dictate the use of free flaps and permit a one stage debridement, flap coverage, and a simultaneous reconstruction of lost functional units.
Conclusion Free flap coverage in high velocity acute facial trauma defects offers a better possibility for primary reconstruction of associated facial injuries and helps in achieving better functional outcomes.
‘The first, but not the last’: women’s descriptive and substantive representation in the 2021 Scottish Parliament election
Authors: Belknap Emilia , Kenny Meryl 
Published: November 2023

AbstractThe 2021 Scottish Parliament election delivered the most diverse range of MSPs in Holyrood’s history, including a record number of women. We situate the 2021 election within its wider context, evaluating dynamics of party feminisation over time. Drawing on original candidate data and analysis of party manifestos across the main Scottish parties, we assess parties’ substantive appeals to women voters; the integration of different groups of women as candidates, MSPs and leaders; and the adoption and implementation of gender quotas. We find evidence of descriptive and substantive party feminisation in Scotland over time—including increases in both the amount and diversity of party manifesto pledges directed at women voters; improvements in the number and diversity of women selected and elected; and the increasing diffusion of, and inter-party competition over, gender quota measures. Yet we also find that progress has been uneven across parties and that some groups of women continue to be descriptively and substantively under-represented in Scottish politics.
Friction or cooperation? Boosting the global economy and fighting climate change in the post-pandemic era
Authors: Yang Zhenshan , Wei Jianan , Ge Quansheng 
Published: November 2023

AbstractIn the post-COVID-19 pandemic era, the world faces a choice between trade protection and cooperation. However, current literature provides very little information on the benefit or loss of trade friction or cooperation on global economy and climate mitigation. This study applied the Global Trade Analysis Project model to assess the impacts of trade friction on global economic recovery and climate change. The results indicated that international trade friction can both delay global economic recovery and affect CO2 emission reduction. The shocks of consumption reduction and production suspension have a higher marginal effect in developing and emerging economies, whereas trade friction has a higher effect on developed countries. Trade friction has more negative economic effects for developed countries, but developing countries cannot reduce CO2 emissions proportionally with the decrease in trade and related production. In the post-pandemic era, if the global trade barrier increases, the world may face a co-occurring economic decline and an increase in or low abatement of carbon emissions.
How do online users respond to crowdsourced fact-checking?

Published: November 2023

AbstractRecently, crowdsourcing has been proposed as a tool for fighting misinformation online. Will internet users listen to crowdsourced fact-checking, and how? In this experiment we test how participants follow others’ opinions to evaluate the validity of a science-themed Facebook post and examine which factors mediate the use of this information. Participants observed a post presenting either scientific information or misinformation, along with a graphical summary of previous participants’ judgements. Even though most participants reported not having used information from previous raters, their responses were influenced by previous assessments. This happened regardless of whether prior judgements were accurate or misleading. Presenting crowdsourced fact-checking however did not translate into the blind copying of the majority response. Rather, participants tended to use this social information as a cue to guide their response, while also relying on individual evaluation and research for extra information. These results highlight the role of individual reasoning when evaluating online information, while pointing to the potential benefit of crowd-sourcing-based solutions in making online users more resilient to misinformation.
Learning by Doing: Educational Tourism at Mount Danxiashan
Authors: Li Guiqing , Xu Ding 
Published: November 2023

Summary
Educational tourism is a fast-growing market in China. Since Mount Danxiashan was listed as a Global Geopark and World Heritage Site in 2010, educational tourism has rapidly grown in the local community, becoming a flagship tourism product. This makes Mount Danxiashan an informative case for understanding educational tourism development and community participation. The present case study has two foci. First, we articulate the stakeholder collaboration mode at Mount Danxiashan. Various stakeholders, including but not limited to the administrative authority, research and education institutes, and local communities, co-determined to develop educational tourism as the best practice for local resources. The collaboration mode and the educational focus are critical in sustaining local development. Second, we depict the learning trajectory of the local community. Led by local intellectual elites, residents acquired both tourism- and nature-related knowledge and participated in educational tourism. This enabled them to design and deliver nature and heritage education curricula for tourists. Moreover, this process encouraged and empowered villagers to co-create new knowledge.
