Why do firms fail? A new view on bankruptcy from the angle of top management team heterogeneity
Authors: Geulen Michael , Greven Andrea , Fischer-Kreer Denise , Brettel Malte 
Published: December 2023

AbstractAvoiding bankruptcy is a crucial task for any firm’s top management team (TMT), and reasons for the failure to accomplish it have long been studied. While financial metrics can predict near-term bankruptcy, governance characteristics increase precision in the long term. With TMT heterogeneity, we introduce a powerful predictor for the critical time frame in between. Grounded in upper echelons theory, we argue that TMT age heterogeneity increases while heterogeneity in TMT pay and TMT functional backgrounds decreases the bankruptcy probability. We test our hypotheses using a unique dataset of large, public U.S. firms, about half of which filed for bankruptcy between 2001 and 2020. Our results support our research model and show how TMT heterogeneity significantly predicts bankruptcy. We contribute to both bankruptcy and strategic management research by underscoring the importance of TMT heterogeneity as a level of analysis when predicting bankruptcy and add to the ongoing discussion on the impact of TMT pay differences on firm performance. Additionally, we offer valuable insights to practitioners navigating their firms in times of crisis and to regulators shaping the insolvency statutes of the future.
Implications of Sex Differences on the Treatment Effectiveness in Heart Failure with Reduced Ejection Fraction Related to Clinical Endpoints and Quality of Life

Published: December 2023

Abstract
Purpose of the Review
This narrative review will emphasize the necessity for more female enrollment in heart failure (HF) trials and proposes future investigations regarding optimal dosages. Ultimately, a deeper understanding of the unique pathophysiology and medication responses in both men and women is crucial for effective HF management and may improve the quality of life in women.

Recent Findings
An analysis of 740 cardiovascular studies reveals that women make up only 38.2% of participants on average. Regarding to trials testing the effectiveness of HF medications, women’s involvement are as low as 23.1%. While current guidelines lack sex-specific treatment recommendations, emerging research suggests differential medication dosages could be beneficial. Studies indicate that women may achieve comparable outcomes with lower doses of certain medications (angiotensin-receptor blockers) compared to men, signaling potential for more tailored dosing approaches.

Summary
We advocate that the next step in HF research should prioritize the importance of tailoring treatment for HF patients by taking into account the variations in drug absorption and distribution among women.

Published: December 2023

AbstractMass transfer can tune the surface concentration of reactants and products and subsequently influence the catalytic performance. The morphology of nanomaterials plays an important role in the mass transfer of reaction microdomains, but related studies are lacking. Herein, a facile electrospinning technique utilizing cellulose was employed to fabricate a series of carbon nanofibers with different diameters, which exhibited excellent electrochemical nitrate reduction reaction and oxygen evolution reaction activities. Furthermore, the microstructure of electrocatalysts could influence the gas–liquid–solid interfacial mass transfer, resulting in different electrochemical performances.

Targeting dysregulated lipid metabolism in the tumor microenvironment
Authors: Kim Do-Hee , Song Na-Young , Yim Hyungshin 
Published: December 2023

AbstractThe reprogramming of lipid metabolism and its association with oncogenic signaling pathways within the tumor microenvironment (TME) have emerged as significant hallmarks of cancer. Lipid metabolism is defined as a complex set of molecular processes including lipid uptake, synthesis, transport, and degradation. The dysregulation of lipid metabolism is affected by enzymes and signaling molecules directly or indirectly involved in the lipid metabolic process. Regulation of lipid metabolizing enzymes has been shown to modulate cancer development and to avoid resistance to anticancer drugs in tumors and the TME. Because of this, understanding the metabolic reprogramming associated with oncogenic progression is important to develop strategies for cancer treatment. Recent advances provide insight into fundamental mechanisms and the connections between altered lipid metabolism and tumorigenesis. In this review, we explore alterations to lipid metabolism and the pivotal factors driving lipid metabolic reprogramming, which exacerbate cancer progression. We also shed light on the latest insights and current therapeutic approaches based on small molecular inhibitors and phytochemicals targeting lipid metabolism for cancer treatment. Further investigations are worthwhile to fully understand the underlying mechanisms and the correlation between altered lipid metabolism and carcinogenesis.
Market engagement, crop diversity, dietary diversity, and food security: evidence from small-scale agricultural households in Uganda
Authors: Morrissey Katherine , Reynolds Travis , Tobin Daniel , Isbell Carina 
Published: December 2023

AbstractSmall-scale farmers make up the majority of farmers worldwide yet experience particularly high rates of food insecurity. A growing body of literature explores pathways to food and nutrition security among small-scale farmers but has yet to reach consensus on the most effective pathways (e.g., crop specialization for market sale versus on-farm crop diversification for home consumption) to improve livelihoods. Using structural equation modelling (SEM) based on data drawn from the 2015/16 Uganda National Panel Survey, this study considers how farm and household characteristics including gender, age, education, farm size, region, and off-farm income relate to market engagement (farm sales, market purchases) and on-farm crop diversity (Simpson’s diversity). We then further examine how market engagement and on-farm crop diversity relate to household livelihood outcomes including dietary diversity and food security (number of food secure months). Findings suggest that both higher levels of market engagement and on-farm crop diversity are associated with increased dietary diversity. Higher levels of crop diversity—whether for market sale or for self-consumption—are strongly associated with improved food security. Market engagement is positively associated with increased dietary diversity, and this association is particularly strong for market purchases. Together, these findings highlight the potential for both market-based strategies and on-farm crop diversity to contribute to food security goals in Uganda, providing further evidence that these strategies can be complementary.
A COVID-19 stress test for life insurance: insights into the effectiveness of different risk mitigation strategies
Authors: Hanika Moritz 
Published: December 2023

AbstractCOVID-19 has affected mortality rates and financial markets worldwide. Against this background, we perform a COVID-19 stress test for life insurance, considering a joint financial and mortality shock, to evaluate the effectiveness of different risk mitigation strategies. Specifically, we conduct a model-based simulation analysis of a life insurer selling annuities and term life insurances. The analysis includes stress scenarios that are calibrated to observations during the first year of the COVID-19 pandemic. We also consider new business and study the risk situation under three different risk mitigation strategies observed in practice as an immediate response to the pandemic: stopping sales, increasing premiums, or adjusting investment strategies. Results show that a life insurer’s risk situation is mainly affected in the short term, selling annuities (in addition to term life insurance) immunizes against the mortality shock, and the immediate use of risk mitigation strategies can help reduce the negative impact.
Integrating image processing and deep learning for effective analysis and classification of dust pollution in mining processes

Published: December 2023

AbstractA comprehensive evaluation method is proposed to analyze dust pollution generated in the production process of mines. The method employs an optimized image-processing and deep learning framework to characterize the gray and fractal features in dust images. The research reveals both linear and logarithmic correlations between the gray features, fractal dimension, and dust mass, while employing Chauvenel criteria and arithmetic averaging to minimize data discreteness. An integrated hazardous index is developed, including a logarithmic correlation between the index and dust mass, and a four-category dataset is subsequently prepared for the deep learning framework. Based on the range of the hazardous index, the dust images are divided into four categories. Subsequently, a dust risk classification system is established using the deep learning model, which exhibits a high degree of performance after the training process. Notably, the model achieves a testing accuracy of 95.3%, indicating its effectiveness in classifying different levels of dust pollution, and the precision, recall, and F1-score of the system confirm its reliability in analyzing dust pollution. Overall, the proposed method provides a reliable and efficient way to monitor and analyze dust pollution in mines.

Published: December 2023

AbstractWater and mud inrush caused by fault is a geological disaster characterized by high frequency and huge destructiveness. It is important to study the evolutionary laws of water inrush in fault fracture zones with various filling types. The effect of filling gradation on the mesoscopic structure and seepage characteristics of fault fracture zones was investigated. The law of water inrush evolution and water inrush characteristics of fault-fractured zones with different filling gradations and strong zoning filling characteristics were studied. The results showed that for the larger Talbot gradation indices, the mass of water inrush and the fractal dimension of the lost particles were larger, the peak water pressure and the mass of the lost particles were smaller, and the duration of the initial impermeability stage was shorter for the same loading water pressure. For the fault fracture zones with strong zoning filling characteristics, the peak water pressure, the mass of water surges, and the mass of lost particles were larger, the fractal dimension of the lost particles was smaller, and the duration of the initial impermeability stage was shorter for the fracture zones with larger filling gradation were used as the initial impermeability zones. Furthermore, with larger filling gradation, we observed a greater proportion of large pores, a larger equivalent throat radius, higher pore connectivity, and coordination numbers. Filling gradation and confining pressure greatly affected the permeability of the fault. The permeability decreased by 98.71% when the Talbot gradation indices decreased from 1.25 to 0.6, and decreased by 58.4% when the confining pressure increased from 5 MPa to 15 MPa.
Failure precursor characteristics of different types of rocks under load: insights from critical slowing down of acoustic emission
Authors: Ou Jianchun , Wang Enyuan , Wang Xinyu 
Published: December 2023

AbstractIn this study, uniaxial compression tests and simultaneous acoustic emission (AE) monitoring were carried out on four rocks (yellow sandstone, white sandstone, marble and limestone). The mechanical properties and AE energy evolution characteristics of different rocks were analysed. With the help of critical slowing down (CSD) theory, the AE precursor characteristics of their failure were investigated. It is pointed out that the AE during rock loading has a CSD phenomenon. A sudden change in the variance of one of the CSD indicators can be regarded as a precursor to failure, and it has the advantage of being more accurate and sensitive to failure than the autocorrelation coefficient. The stress level of a rock's failure precursor is closely related to its brittleness characteristics. The higher the brittleness of the rock, the more backward the failure precursor is, and the more difficult the early warning is. The study aims to provide new indicators and references for the monitoring and early warning of rockbursts and other disasters induced by rock fracture in deep underground engineering.

Published: December 2023

Abstract
Purpose
The aim of this work is to study the frequency response of linear and nonlinear piezoelectric vibration energy harvester (pVEH) based on Duffing-type nonlinearity and Kirchhoff’s law, and the effect of the effective electromechanical coupling on the frequency response of nonlinear pVEH.

Methods
The analytical technique based on the harmonic balance method (HBM) is used to obtain the mechanical and electrical frequency responses of linear and nonlinear pVEH, and the Jacobian matrix is used to analyze the solutions’ stability. The Runge–Kutta fourth-order method as a numerical technique is used to solve the ordinary differential equations of pVEH.

Results
The analytical calculations are completed, and the frequency response solution of displacement of pVEH is contained in real and complex values and those of electrical responses are presented. The harmonic balance results are compared with numerical simulations for various hardening nonlinear springs. Simple analytical expressions for the jump points are suggested for the sweep-up and sweep-down frequencies of pVEH.

Conclusions
The analytical analysis shows that the jump-down frequency ratios have definite behaviors for each low and high effective electromechanical coupling of hardening-nonlinear pVEHs. Moreover, the jump-up frequency ratio is directly proportional to the effective electromechanical coupling of hardening nonlinear pVEHs.

Published: December 2023

Abstract
Introduction
Slight lateral laxity exists in normal knee especially in flexion. The lateral laxity in flexion has possibility to affect the outcome after total knee arthroplasty (TKA).

Purpose
The purpose of this study was to determine how intraoperative laxity in flexion affects patient-reported outcome after total knee arthroplasty.

Methods
We retrospectively analysed 98 knees with osteoarthritis that underwent total knee arthroplasty. After bone resection, ligament imbalance and joint component gaps were measured using an offset-type tensor while applying a 40-lb joint distraction force at 0° and 90° of knee flexion. The lateral laxity in flexion was determined by subtracting polyethylene insert thickness from the lateral gap at 90°. All patients were divided into three groups: ≤ 2 mm (A), 2–5 mm (B), and > 5 mm (C). One year after surgery, patients were asked to fill out questionnaires using the new Knee Society Score after examination outside the consultation room.

Results
The mean intraoperative lateral laxities at 90° were − 0.2 ± 2.1 mm, 3.5 ± 0.7 mm, and 6.7 ± 1.9 mm in groups A, B, and C, respectively. The symptom score of group C was significantly lower than those of groups A or B. There were no significant differences in terms of satisfaction or the expectation and activity scores among all groups. There were no significant differences in terms of alignment after total knee arthroplasty among all groups.

Conclusions
Excessive lateral laxity possibly resulted in worse patient-reported outcomes. However, slight lateral laxity of 2–5 mm might have no effect on patient-reported outcome and this slight varus imbalance could be acceptable. Altogether, our findings would lead to avoidance of excessive medial release in soft tissue balancing.
Estimation of future storm surge inundation and effects of the adaptation measures in Qingdao, China

Published: December 2023

AbstractThe ADvanced CIRCulation (ADCIRC) model was applied to the sea area surrounding Qingdao, China, to estimate the impact of climate change on storm surge and inundation induced by eight typical typhoons in current and future scenarios. Model results were validated using the available observations. These results indicate that the storm surge caused by typhoons with different intensities and paths has various effects on the Qingdao area. Furthermore, measurement results of the storm inundation area in the future scenario revealed that, in any case, with the future rise in sea level, the typhoon intensity, the inundation area, and the storm surge intensity increase. In response to changes in the storm surge and the actual situation in Qingdao, this study emphasized that coastal flooding is caused by the storm surge. Three adaptation measure scenarios were set as follows: the current level of adaptation measures (CLA), the continuation level of adaptation measures (CA), and the enhanced level of adaptation measures (EA). Based on different scenarios, the CA will reduce most of the inundation area caused by coastal flooding compared with the CLA. EA is the most significant in reducing inundation, demonstrating a decrease in inundation of more than 50%. This research has shown that good coastal protection will reduce most coastal flooding, and building dams will be considered a significant adaptation measure.

Published: December 2023

AbstractThe escalation in global consumer demand has prompted the continual expansion of container throughput, which drives container terminals to bolster their production capacities. Globally, ports worldwide have been adopting automated equipment and embracing digital operational environments to reinforce their logistics system efficiency and curtail transportation costs. Enhancement of the efficiency of container transportation at automated terminals depends on terminal loading and unloading operations. The efficiency of these operations directly hinges on the automated mechanical equipment deployed at terminals. Consequently, optimization of resource allocation and production scheduling of loading and unloading equipment at terminals has become an essential and effective approach. In this regard, automated yard cranes, which are responsible for rear-end handling, and automated guided vehicles (AGVs), which transport containers between the yard and the terminal quay, have been proven indispensable. This paper principally delves into the scheduling optimization of mechanical equipment in automated container terminal yards, with a unique focus on the coordinated scheduling optimization of yard cranes and AGVs while also accounting for AGV path planning. This research centers on the automated container terminal yard system and the challenge in yard crane scheduling. This work also establishes a grid-based terminal network model and validates the model and algorithm using practical examples. Optimal solutions are obtained for the joint scheduling of yard cranes and AGVs, accompanied by strategies on rational AGV path selection. The findings provide valuable references and theoretical underpinnings for operational scheduling and enhancement of the efficiency in container transport in automated container terminal yards. Furthermore, these results facilitate the overall improvement of production efficiency at automated terminals and the reduction of operational costs, thus carrying theoretical and practical significance.

Ground-penetrating radar as a tool for determining the interface between temperate and cold ice, and snow depth: a case study for Hurd-Johnsons glaciers, Livingston Island, Antarctica
Authors: Letamendia Unai , Navarro Francisco , Benjumea Beatriz 
Published: December 2023

AbstractWe analyze the internal structure of two polythermal glaciers, Hurd and Johnsons, located on Livingston Island, Antarctica, using 200 and 750 MHz GPR data collected in 2003/04, 2008/09 and 2016/17 field campaigns. Based on the different permittivities of snow and ice, we determined the thickness distribution of the end-of winter snow cover and of the cold ice layer. Their knowledge is fundamental for mass balance and glacier dynamics studies due to the different densities and rheological properties of such media. The average measured thicknesses for the snow and cold ice layers (the latter including the snow layer) were of 1.44 ± 0.09 and 29.1 ± 1.5 m, and their corresponding maxima were of 2.45 ± 0.21 and 80.8 ± 2.5 m. GPR snow profiling allowed for extension of the coverage of the snow thickness survey, but added little information to that supplied by snow pits, stake readings and manual snow probing, because of the multiplicity of reflections within the seasonal snowpack caused by internal ice layers and lenses. The polythermal structure determined for Hurd Glacier fits into the so-called Scandinavian type, seldom reported for the Antarctic region.
