Published: December 2023

AbstractIn recent years, studies have put forth various theories on the role of oceanic equatorial Rossby waves (OERW) in the subseasonal‐to‐seasonal (S2S) predictability of the Indian Ocean (IO). While much of the scientific literature uses data from in‐situ, satellite, and/or reanalysis datasets, this study focuses on reforecast fields from the European Centre for Medium‐Range Weather Forecasting's (ECMWF) S2S dataset. Evaluation of the model's predictive skill in representing OERWs and the associated variations in subsurface‐to‐surface interaction and air–sea coupling are discussed. This work provides a unique methodology to calculate and evaluate the predictability of OERWs from model forecast data. Our results indicate that the model forecasts OERWs with high skill (anomaly correlation > 0.8 out to 40 days), indicating they are a key source of oceanic subseasonal predictability at extended lead times. Analysis of the wavenumber–frequency spectra for the IO indicates a strong reduction in power throughout the model forecast time period in the oceanic equatorial Kelvin wave (OEKW) regime and modest reduction of the OERW power. Both Kelvin and Rossby waves are modulated by the subseasonal zonal wind stress anomalies and the reduction of power is impacted by biases in winds at longer forecast leads. The erroneous weakening of the OEKWs contributes to the weakening of the reflected OERWs. Previous studies have documented that ocean heat content (OHC), particularly associated with downwelling OERWs, is important to maintaining and amplifying subseasonal precipitation in the IO. The reduced OERW power results in weaker advection of enhanced OHC anomalies by the OERWs, which has numerous implications for air–sea and subsurface‐to‐surface coupling, as discussed. The atmospheric response to the waning westward transport of OHC anomalies in the western IO by OERWs is associated with a weakening of intraseasonal precipitation anomalies associated with the intraseasonal oscillation.

AbstractObjectiveTo compare intrauterine pressure generated during pushing as measured by an intrauterine pressure catheter in the first and second stages of labor in obese patients (body mass index [BMI] ≥ 35 kg/m2) and nonobese (BMI < 35 kg/m2).MethodsThis was a prospective observational study of patients in labor at term. Peak intrauterine pressure was measured during a Valsalva maneuver in the first and second stages of labor, both during a contraction and at rest and compared between obese and nonobese patients. Pushing pressure, defined as the mean of the highest three out of five peak pressures attained minus the intrauterine resting pressure were also compared for the two groups.ResultsA total of 115 patients were enrolled: 50 (43.5%) obese and 65 (56.5%) nonobese. We found pushing pressures were significantly less in obese patients both with risk difference (RD) = 13.71 (95% confidence interval [CI]: 5.53, 21.90) and without RD = 12.19 (95% CI: 4.46, 19.91) a uterine contraction compared to the nonobese patients in the second stage of labor. This effect persisted after controlling for confounding variables.ConclusionObese patients with BMI ≥ 35 kg/m2 generated lower intrauterine pressures during pushing than compared to nonobese (BMI < 35 kg/m2). This suggests that obese patients may need a longer second stage of labor or a longer duration of pushing to achieve vaginal birth.

Published: December 2023

AbstractThis article addresses the distributed robust fault‐tolerant control design problem for networked Euler–Lagrange (EL) systems with time‐varying delays under directed communication topologies. The leaderless and leader‐follower consensus is established. In order to eliminate the influence of actuator faults and external disturbances on the system performance, some designer‐specified performance constraints are imposed on the sliding variables rather than the tracking errors. Based on the variable transformation, two kinds of fault‐tolerant control schemes are proposed under the prescribed constraints. The stability of the closed‐loop systems with time delays is analyzed, and it is shown that the sliding variables eventually converge within an arbitrarily small boundary range. Simulation studies are presented to exhibit the effectiveness of the proposed control schemes.

AbstractNitrogen (N) fertilizer management continues to be challenging due to potential nitrogen losses under variable weather conditions. This study aimed to evaluate the performance of nitrification inhibitors, nitrogen sources, and herbicides on in‐season nitrogen availability and agronomic indicators. A 2 site‐year field experiment was conducted in silty‐clay loam soil in the maize (Zea mays L.) phase of a maize–soybean rotation in Central Nebraska. The study included two herbicide treatments (Acuron and Resicore) and four nitrogen treatments: (1) anhydrous ammonia with a nitrification inhibitor, (2) anhydrous ammonia without a nitrification inhibitor, (3) urea with a nitrification inhibitor, and (4) urea without a nitrification inhibitor. Nitrogen sources had a more significant effect on NH4+‐N retention (300%–340% higher in anhydrous ammonia vs. urea) than nitrification inhibitors (14%–50% higher with inhibitor vs. without inhibitor) and herbicides. Similarly, nitrogen sources significantly affected NO3−‐N formation (58%–64% lower in anhydrous ammonia vs. urea) compared with nitrification inhibitors (7%–27% lower with inhibitor vs. without inhibitor) and herbicides. Nitrification inhibitors did not affect agronomic indicators. However, anhydrous ammonia increased grain yield by 1.1 Mg ha−1, partial factor productivity by 6 kg grain kg−1 N, agronomic efficiency by 5.5 kg grain kg−1 N, aboveground biomass N‐uptake by 34 kg N ha−1, grain N‐uptake by 15 kg N ha−1, nitrogen recovery efficiency by 33%, and residual total inorganic N by 6–40 kg N ha−1 compared to urea. These findings suggest that using the right fertilizer source, followed by nitrification inhibitor and herbicide, can be an effective strategy for conserving nitrogen and improving nitrogen use efficiency in maize.
A machine learning oracle for parameter estimation

Published: December 2023

AbstractCompeting procedures, involving data smoothing, weighting, imputation, outlier removal, etc., may be available to prepare data for parametric model estimation. Often, however, little is known about the best choice of preparatory procedure for the planned estimation and the observed data. A machine learning‐based decision rule, an “oracle,” can be constructed in such cases to decide the best procedure from a set of available preparatory procedures. The oracle learns the decision regions associated with based on training data synthesized solely from the given data using model parameters with high posterior probability. An estimator in combination with an oracle to guide data preparation is called an oracle estimator. Oracle estimator performance is studied in two estimation problems: slope estimation in simple linear regression (SLR) and changepoint estimation in continuous two‐linear‐segments regression (CTLSR). In both examples, the regression response is given to be increasing, and the oracle must decide whether to isotonically smooth the response data preparatory to fitting the regression model. A measure of performance called headroom is proposed to assess the oracle's potential for reducing estimation error. Experiments with SLR and CTLSR find for important ranges of problem configurations that the headroom is high, the oracle's empirical performance is near the headroom, and the oracle estimator offers clear benefit.
Investigating the relationship between energy‐consuming rights trading and urban innovation quality
Authors: Guo Bingnan , Hu Peiji 
Published: December 2023

AbstractThe Energy‐consuming rights trading policy (ECRTP) is an important environmental regulatory policy in China. The study's goal is to determine how trading in energy‐consuming rights and urban innovation status effects also promote ecological civilization and high‐quality development. The purpose of the study examines the relationship between ECRTP and urban innovation quality (UIQ). Using data from 271 Chinese cities between 2011 and 2020, a difference‐in‐difference (DID) model is used to theoretically and empirically analyze the effects of ECRTP on UIQ. The findings of the study are as follows: First, ECRTP showed a significant improvement in UIQ, although a lagged effect. This outcome offers fresh proof that the “Porter hypothesis” holds water in China. Second, mechanism analysis indicated that ECRTP could improve UIQ with industrial structure upgrading (ISU) and capital deepening. Third, analysis of spillover effects indicates that ECRTP has a key spillover impact on UIQ. Analysis of spillover effects indicates a positive influence of ECRTP on UIQ in surrounding cities. Fourth, heteroggeneity analysis further reveals the impact of ECRTP on UIQ is particularly pronounced in resource‐based and large‐scale cities. These findings are significant and also provide a valuable supplement to the existing study.
Asserting and transcending ethnic homophily: How entrepreneurs develop social ties to access resources and opportunities in socially contested environments
Authors: Busch Christian , Mudida Robert 
Published: December 2023

AbstractResearch SummaryIn socially contested settings, it is often difficult to connect with (diverse) others, and it is unclear how entrepreneurs in these contexts may develop the social ties that previous research has shown to be valuable. We studied this subject matter in Kenya, an ethnically fractionalized society that recently experienced the decentralization of government, which required entrepreneurs to deal with both in‐group and out‐group ethnicities. We conducted an inductive case study of four Nairobi‐based companies and captured the creative tactics that they used to transcend ethnic homophily (by defocusing from ethnicity and reframing the in‐group) while also asserting ethnic homophily (by signaling tribal affiliation and leveraging others' ethnicity). We contribute to a deeper understanding of how and why entrepreneurs in socially contested settings develop social ties.Managerial SummaryEntrepreneurs in socially contested settings rely on social networks to access resources and opportunities. However, it is unclear how entrepreneurs in these settings develop and use these networks. We studied this question in an ethnically fractionalized setting that recently experienced the decentralization of government: Kenya. Entrepreneurs who previously provided information technology (IT) services to the central government had to deal with both own‐tribe and other‐tribe contacts to receive new contracts. We studied four Nairobi‐based IT firms that operated across a variety of counties and analyzed the creative tactics that entrepreneurs in this context use to cross ethnic divides while also working with own‐tribe contacts. This contributes to our collective understanding of how and why entrepreneurs in socially contested settings develop diverse social ties to access resources and opportunities.
A cloud‐edge service offloading method for the metaverse in smart manufacturing

Published: December 2023

SummaryWith the development of artificial intelligence, cloud‐edge computing and virtual reality, the industrial design that originally depends on human imagination and computing power can be transitioned to metaverse applications in smart manufacturing, which offloads the services of metaverse to cloud and edge platforms for enhancing quality of service (QoS), considering inadequate computing power of terminal devices like industrial sensors and access points (APs). However, large overhead and privacy exposure occur during data transmission to cloud, while edge computing devices (ECDs) are at risk of overloading with redundant service requests and difficult central control. To address these challenges, this paper proposes a minority game (MG) based cloud‐edge service offloading method named COM for metaverse manufacturing. Technically, MG possesses a distribution mechanism that can minimize reliance on centralized control, and gains its effectiveness in resource allocation. Besides, a dynamic control of cut‐off value is supplemented on the basis of MG for better adaptability to network variations. Then, agents in COM (i.e., APs) leverage reinforcement learning (RL) to work on MG history, offloading decision, QoS mapping to state, action and reward, for further optimizing distributed offloading decision‐making. Finally, COM is evaluated using a variety of real‐world datasets of manufacturing. The results indicate that COM has 5.38% higher QoS and 8.58% higher privacy level comparing to benchmark method.

AbstractIn today's cybersphere, cryptography plays a vital role in various fields. Image encryption is an integral part for securing information because of its vast application areas such as military (defense), multimedia, healthcare and so forth. In this article, an image encryption algorithm for both grayscale and color image is proposed based on Tangential Delay‐Ellipse Reflecting Curve System (TD‐ERCS) chaotic map system and deoxyribonucleic acid (DNA) coding. Chaotic map is used to scramble the pixel positions; to achieve confusion and for creation of mask image, and DNA coding is used for changing the pixel values; to achieve diffusion. Upon experimental analysis, proposed work achieved significantly high mean square error and low peak signal to noise ratio, almost zero correlation, high number of pixel change rate and unified averaged changed intensity values, and resistance to noise and data loss attacks. In addition, the decryption is possible without loss in quality of image.

SummaryTraditional wooden structures are characterized by the presence of a column base that seems to be floated above the foundation stone. This study used pseudo‐static experiments to assess the seismic performance of flat pendulum floating resting columns, focusing on the decay and repair of the wood frame (WF). First, an artificial method was used to simulate fungal decay damage of column‐foot joints, and filling reinforcement was applied to the decayed column‐foot joints, and second, according to the design method in the Sung dynasty architecture, the Ying‐tsaofa‐shih (building standards). This study presents the findings of pseudo‐static tests that were conducted at Yangzhou University. Three 1:3.52 scaled specimen WFs with flat‐pendulum‐floating‐shelf (FPFS)‐typed (Ping‐bai‐fu‐ge) columns, i.e., non‐damaged WF (named after NT), considering the damaged WF (named after DF) and strengthening damaged WF (named after DR) with one‐way straight mortise‐tenon joints (OWSMT) joints were made and subjected to cyclic lateral loads during testing. The properties of the WFs with FPFS columns, such as the failure mode, hysteretic and envelope curves, strength and stiffness deterioration, and energy dissipation, have been studied. Finally, the effects of additional damage and reinforcement measures on the seismic performance of WFs are analyzed and compared with the finite element numerical simulation results. This research shows that damage to the column foot decreases the WF's seismic performance, although filler reinforcement may increase it. The foot and mortise joints are interconnected and interact in the wood frame's seismic stressing mechanism. Foot decay reduces the seismic performance of the foot joint, hence increasing the seismic energy dissipation activity of the mortise joints.
RETRACTED: USP14 promotes the proliferation of cervical cancer via upregulating β‐catenin

Published: December 2023

AbstractIn recent years, the ubiquitin–proteasome system (UPS) has become a hot spot in medical research in cervical cancer (CC) and has received extensive attention. Among them, ubiquitin‐specific protease 14 (USP14) is involved in a wide variety of typical cell signaling pathways and is recognized to be involved in the progression of most known tumors. However, the expression and significance of USP14 in CC have not been directly studied. Through database analysis, we found that USP14 was overexpressed in CC, which influenced the FIGO stage and prognosis of CC patients, and it was positively correlated with the expression level of β‐catenin. In this study, USP14 promoted the G1‐S phase transition of Hela and Siha cells and inhibited cell apoptosis, thereby promoting the proliferation, migration, and invasion of CC cells. In addition, USP14 also significantly promoted the growth of subcutaneous tumor in nude mice. We also found that overexpression of USP14 significantly upregulated β‐catenin expression and increased the activity of Wnt/β‐catenin signaling pathway. While knockdown of USP14 resulted in the opposite. These results suggest that USP14 may promote the proliferation of CC by up‐regulating the expression of β‐catenin, contributing to a deeper understanding of the mechanisms of CC and providing a potential therapeutic target.

Published: December 2023

AbstractAgrochemicals cause diverse effects on aquatic communities, and amphibian species are particularly threatened due the high susceptibility to contamination. Present study evaluates the toxicity of a widely used fungicide tebuconazole (Trigal®) by the assessment of mortality and developmental alterations at acute, subchronic, and chronic exposure during the embryo‐larval development of the South American toad Rhinella arenarum. Also, the sensitivity of the different embryonic stages was evaluated with 24‐h pulse exposure treatments. The results demonstrated that larvae were more sensitive than embryos at acute exposure (LC50‐24 and 96 h = 74.62, 31.92 mg/L and 24.27, 16.81 mg/L for embryos and larvae, respectively). Nevertheless, embryos toxicity increased significantly achieving a sensitivity very similar to larvae at chronic exposure (LC50‐168 and 504 h = 13.31, 4.35 mg/L and 14.47, 6.83 mg/L for embryos and larvae, respectively). Embryos exhibited several sublethal effects from 5 mg/L at 96 h onwards, such as delayed development, reduce body size, edemas, tail/axial flexures, weakness, and absence of movements. The teratogenic index at 96 h was 10.13, indicating the severe teratogenic potential of the fungicide. 24‐h pulse exposure treatments showed an increased sensitivity in intermediate stages as S.11, S.18, S20, and S.23 (NOEC‐96 h = 100, 200, 75, and 20 mg/L, respectively), while stage S.25 was the most sensitive to the fungicide (NOEC‐96 h = 5 mg/L). About metamorphic process, tebuconazole caused an acceleration of metamorphosis at the lowest concentration (0.001 mg/L), but also an increase in mortality and in addition, significant differences in the weight in all treatments. The results obtained throughout this work indicate that tebuconazole cause several adverse effects in Rhinella arenarum embryo‐larval development.
The Institutionalization of the Social Sciences in Mexico 1930–1959
Authors: Zabludovsky Gina 
Published: December 2023

AbstractThe first decade of this time period was characterized by the central importance of Lazaro Cardenas’s presidency (1934–1940), including his reforms that sought to promote equality in land ownership in the countryside and his support for the immigration of Spanish republicans, which would have an important intellectual influence in the development of social sciences and humanities in Mexico. The second decade, during the presidential periods of Avila Camacho (1940–1946) and Miguel Aleman (1946–1952) saw economic policies that promoted the industrialization and urbanization of the country, which was often described as the “Mexican Miracle.” Sociology went through an institutionalization process with the founding of research institutions, editorial houses, specialized journals, and bachelor’s programs.
Narbenhernien: minimalinvasive Operationsverfahren
Authors: Baur Johannes , Meir Michael 
Published: December 2023

Zusammenfassung
Hintergrund
In den letzten Jahren wurde eine Vielzahl neuer Operationstechniken zur minimalinvasiven Versorgung ventraler Hernien entwickelt und vorgestellt. In dieser Übersichtsarbeit werden diese minimalinvasiven Operationstechniken wie eTEP („extended totally extraperitoneal“), MILOS („mini or less open sublay“), ELAR (endoskopisch assistierte Linea-alba-Rekonstruktion), ventrale TAPP (transabdominelle präperitoneale Patch-Technik), IPOM (intraperitoneales Onlay-Mesh) Plus und LIRA (laparoskopische intrakorporale Rektusaponeuroplastie) vorgestellt und die hierzu relevanten bislang publizierten Ergebnisse präsentiert.

Ergebnisse
Moderne minimalinvasive Techniken zur Behandlung ventraler Hernien bergen das Potenzial einer Reduktion von Wundinfektionen, geringerer postoperativer Schmerzen und einer kürzeren Krankenhausverweildauer im Vergleich zu den klassischen Hernienoperationen. Insbesondere Techniken mit retromuskulärer Netzposition sind aufgrund der Präparation in engen Räumen und aufgrund schwierig durchzuführender endoskopischer Nähte technisch anspruchsvoll und erfordern fundierte Kenntnisse der Anatomie der Bauchwand. Vor allem die Versorgung größerer Hernien sollte daher nur unter der Voraussetzung ausreichender Erfahrung und Fallzahl erfolgen.

Schlussfolgerung
Die neuen, endoskopischen bzw. endoskopisch assistieren Verfahren zur Versorgung ventraler Hernien ermöglichen dem laparoskopisch erfahrenen Chirurgen, primäre und sekundäre ventrale Hernien minimal-invasiv zu versorgen.
