Recently, impressive developments in the field of nanotechnology have been achieved. The study aimed to synthetize zinc oxide nanoparticles (ZnONPs) from locally isolated terrestrial Bacillus paramycoides (MCCC 1A04098) bacteria and assess its role as antioxidant, antimicrobial, and anticancer agent. The antioxidant activity was done using the percentage of DPPH scavenging method. The antibacterial activity was evaluated against Escherichia coli, Staphylococcus aureus, Bacillus cereus, and Candida albicans. The anti-proliferation assay against hepatocellular carcinoma (HepG2) and human breast cancer (MCF-7) cell lines was estimated by neutral red assay. The apoptotic effect of ZnONP was measured by flow cytometry. The in vivo evaluation was carried out against hepatorenal injuries induced by carbon tetrachloride (CCl4) in rats comparing with silymarin as a reference drug. The oxidative stress markers, liver and kidney function enzyme indices, lipid profile, and the histological features of the liver and kidney were also examined. ZnONPs revealed antioxidant and antibacterial effects. It also exerted cytotoxic and apoptotic effect in a dose dependent manner without any toxicity on normal cell line. ZnONPs improved all the biochemical parameters under investigation to varying degrees, and the histological pictures of the liver and kidney confirmed the results. In conclusion, ZnONPs were successfully synthesized from the terrestrial Bacillus paramycoides and recorded in vitro antioxidant, anticancer, and antibacterial effects as well as in vivo anti-hepatorenal toxicity effects.

Graphical Abstract
Delineation of lineaments for groundwater prospecting in hard rocks: inferences from remote sensing and geophysical data
Authors: Embaby Ashraf , Youssef Youssef M. , Abu El-Magd Sherif Ahmed
Published: January 2024

Egypt is grappling with water scarcity challenges, which are exacerbated by extensive urban development in arid coastal regions with rugged terrain. Although desalinated water is an alternative source in the remote Halayeib region of Southeast Egypt, its cost increases reliance on groundwater from the intricate aquifers. This study aims to accurately delineate hydro-structural features, known as lineaments, and assess their impact on the groundwater conditions in this promising region. This integrated approach involves the assessment of various spaceborne sensors, including optical (Landsat 8), Digital Elevation Models (ALOS and ASTER-DEMs), and radar (Sentinel-1), using geospatial and geostatistical techniques within the Geographic Information System (GIS). Radar-based sensors, particularly the Sentinel-1A vertical–vertical (S1A VV) polarization, outperform all other datasets in extracting lineaments, yielding 4883 lineaments that correspond to the regional geological faults. These lineaments trend in NE–SW, NNE–SSW, NW–SE, and E-W directions. The results also indicated that both digital elevation models (DEMs) were less effective, showing different orientations with azimuth angles. S1A VV proved to be highly effective in identifying subsurface fractured hard rock terrains beneath thin sedimentary covers, especially in the flat coastal area of Wadi Serimatai, where they intersected natural drainage pathways. Geoelectrical sections confirmed that there are orthogonal subsurface faults extending from fractured basement aquifers to near-surface layers. These faults align with the NE-SW and NNE-SSW directions observed in S1A VV lineaments. Geostatistical analysis revealed that S1A VV structural lineaments, lithological, and hydrogeological factors influence the occurrence of groundwater. This emphasizes the structural control over groundwater and its significant impact on water flow and storage. The study provides valuable insights for groundwater management, guiding decisions related to the development of groundwater resources.
A Study on Lebanon’s Competitive Knowledge-Based Economy, Relative Strengths, and Shortcomings
Authors: Ben Hassen Tarek
Published: January 2024

Lebanon faces several social, political, and economic challenges delaying the efforts to develop a sustainable economy and inclusive society. The advancement of the knowledge economy is critical to the future economic prosperity of Lebanon. This paper aims to scrutinize the state of the knowledge-based economy in Lebanon, focusing on five pillars, such as education and human capital, entrepreneurship, innovation system, economic and institutional regime, and information and communications technology (ICT), and to present recommendations for future action. The methodology is based on semi-structured face-to-face and phone interviews with stakeholders using two questionnaires. The paper finds that the process of transitioning towards a knowledge-based economy in Lebanon is influenced by two contrasting factors: the education system and the entrepreneurship culture, on the one hand, and the country’s political turmoil, on the other. Indeed, moving toward a knowledge-based economy in Lebanon is supported by its highly qualified and multilingual human resources, which is an outcome of the reliable educational system and reinforced by a robust entrepreneurial spirit. However, several issues, such as weak ICT infrastructure, incompetent public institutions, and the brain drain, hinder the transition to a knowledge-based economy. These results help clarify and critically analyze the present state of the knowledge-based economy in Lebanon, which has various policy implications.
An Investigation on Hydraulic Aspects of Rectangular Labyrinth Pool and Weir Fishway Using FLOW-3D
Authors: Mirkhorli Parisa , Ghaderi Amir , Alizadeh Sanami Forough , Mohammadi Mirali , Kuriqi Alban , Kisi Ozgur
Published: January 2024

Two different arrangements of the weir (i.e., straight weir and rectangular labyrinth weir) were used to evaluate the effects of geometric parameters such as weir shape, weir spacing, presence of an orifice at the weir, and bed slope on the flow regime and the relationship between discharge and depth, variation and distribution of depth-averaged velocity, turbulence characteristics, and energy dissipation at the fishway. Computational fluid dynamics simulations were performed using FLOW-3D® software to examine the effects on flow conditions. The numerical model was validated by comparing the calculated surface profiles and velocities with experimentally measured values from the literature. The results of the numerical model and experimental data showed that the root-mean-square error and mean absolute percentage error for the surface profiles and normalized velocity profiles of plunging flows were 0.014 m and 3.11%, respectively, confirming the ability of the numerical model to predict the flow characteristics of the pool and weir. A plunging flow can occur at values of L/B = 1.83 (L: distance of the weir, B: width of the channel) and streaming flow at L/B = 0.61 for each model. The rectangular labyrinth weir model has larger dimensionless discharge values (Q+) than the conventional model. For the conventional weir and the rectangular labyrinth weir at submerged flow, Q is proportional to 1.56 and 1.47h, respectively (h: the water depth above the weir). The average depth velocity in the pool of a conventional weir is higher than that of a rectangular labyrinth weir. However, for a given discharge, bed slope, and weir spacing, the turbulent kinetic energy (TKE) and turbulence intensity (TI) values are higher for a rectangular labyrinth weir compared to conventional weir. The conventional weir has lower energy dissipation than the rectangular labyrinth weir. Lower TKE and TI values were observed at the top of the labyrinth weir, at the corner of the wall downstream of the weir, and between the side walls of the weir and the channel wall. As the distance between the weirs and the bottom slope increased, the average depth velocity, the average value of turbulent kinetic energy and the turbulence intensity increased, and the volumetric energy dissipation in the pool decreased. The presence of an opening in the weir increased the average depth velocity and TI values and decreased the range of highest TKE within the pool, resulted in larger resting areas for fish (lower TKE), and decreased the energy dissipation rates in both models.

Authors: Crevits Léna , Silva Catarina , Bat-Pitault Flora
Published: January 2024

Purpose

Insomnia and anorexia nervosa (AN) are frequently comorbid, negatively affecting the evolution and the prognosis of AN. Within this framework, the management of sleep disorders appears as critical. The aim of this retrospective study is to assess, for the first time, the efficacy of cognitive and behavioural therapy for insomnia (CBT-I) on sleep disturbances in adolescents with AN. To do so, we investigated the impact of CBT-I on sleep disturbances and sleep-related outcomes, in BMI, AN symptoms, anxiety and depressive symptoms, emotionality and quality of life. These features were compared between two groups of patients with AN, one following CBT-I, and the other receiving the regular treatment at the psychiatric unit.

Methods

Data collection occurred between January and May 2022. The study included 42 adolescents in-treatment at the Eating Disorders care specialised unit at Salvator Hospital in Marseille. They were randomly assigned to the CBT-I group (N = 31) or the control group (N = 11). Several clinical elements were assessed using sleep diaries and self-report questionnaires.

Results

Participants undergoing CBT-I showed a significant improvement in sleep latency, total wake time and sleep efficacy, as well as in physical well-being. No significant effects were found regarding AN symptoms.

Conclusion

These preliminary findings provide support for CBT-I effectiveness in adolescents with AN, as shown by significant improvements in several sleep parameters, as well as in physical well-being. These promising results, underline the relevance of this topic and its potential benefits for a more appropriate treatment for adolescents with AN.

Recent advances in the treatment for gynecologic oncology
Authors: Li Lei , Lang Jinghe
Published: January 2024

This commentary summarized the most important findings in the first half 2023 year based on Society of Gynecologic Oncology (SGO) annual meeting and publications in crucial journals.

This commentary provided a comprehensive overview of notable developments in the field of gynecologic oncology throughout the first half of 2023, drawing insights from the Society of Gynecologic Oncology (SGO) Annual Meeting and pivotal publications in esteemed journals. The discourse delved into the forefront of molecular mechanisms, emphasizing critical themes such as homologous recombination repair deficiency, mismatch repair, immune checkpoint blockades, and anti-angiogenesis in various cancers. Specific attention was given to advancements in targeted and immunotherapeutic modalities, notably examining the efficacy and safety profiles of poly (ADP-Ribose) polymerase inhibitors (PARPi) in ovarian cancer. Conclusively, the commentary underscored the transformative impact of molecularly guided therapies, marking them as pivotal in addressing refractory conditions and set the stage for heightened expectations in future advancements.

PARP inhibitors have become the standard maintenance treatment for ovarian cancer. Among the first six articles, two (SOLO1 and PAOLA-1) summarized evidence supporting the improvement of overall survival with PARP inhibitors in maintenance therapy, while the NOVA study reported no benefit in overall survival. The first, fourth, and sixth articles discussed the feasibility of PARP inhibitors, immune checkpoint inhibitors used alone or in combination in neoadjuvant therapy (post-chemotherapy surgery). The latter two articles focused on the application of PD-1 (immune checkpoint inhibitors) in locally advanced cervical cancer, demonstrating enhanced efficacy. Currently, immune checkpoint inhibitors are commonly used in advanced cervical and endometrial cancers due to their status as hot tumors. Their use, either alone or in combination with anti-angiogenic drugs, has shown better outcomes in recurrent and advanced refractory endometrial and cervical cancers compared to traditional chemotherapy. A study from Huashan Hospital discussed the effectiveness of immune checkpoint inhibitors combined with anti-angiogenic therapy in recurrent cervical cancer, although there might be a typo as the initial mention was about endometrial cancer. The following article discussed late-stage endometrial cancer, finding no difference in survival between chemotherapy and chemotherapy combined with radiation. Subsequent articles highlighted the superiority of immune checkpoint inhibitors combined with chemotherapy in treating recurrent endometrial cancer, as well as the efficacy of immune checkpoint inhibitors combined with anti-angiogenic therapy in endometrial cancer. The final article focused on the therapeutic effect of HER2-positive ADC class drugs in uterine cancer sarcoma.

Authors: Gillespie Alex , Glăveanu Vlad , de Saint Laurent Constance
Published: January 2024

Taking a pragmatist approach to methods and methodology that fosters meaningful, impactful, and ethical research, this book rises to the challenge of today's data revolution. It shows how pragmatism can turn challenges, such as the abundance and accumulation of big qualitative data, into opportunities. The authors summarize the pragmatist approach to different aspects of research, from epistemology, theory, and questions to ethics, as well as data collection and analysis. The chapters outline and document a new type of mixed methods design called 'multi-resolution research,” which serves to overcome old divides between quantitative and qualitative methods. It is the ideal resource for students and researchers within the social and behavioural sciences seeking new ways to analyze large sets of qualitative data. This book is also available as Open Access on Cambridge Core.
When Politics Becomes Personal
Authors: Bankert Alexa
Published: January 2024

Can we be good partisans without demonizing our political opponents? Using insights from political science and social psychology, this book argues for the distinction between positive and negative partisanship. As such, strong support for a political party does not have to be accompanied by the vilification of the opposing party and its members. Utilizing data from five different countries, Bankert demonstrates that positive and negative partisanship are independent concepts with distinct consequences for political behavior, including citizens' political participation and their commitment to democratic norms and values. The book concludes with the hopeful message that partisanship is an essential pillar of representative and liberal democracy.
Understanding Obesity
Authors: Ulijaszek Stanley
Published: January 2024

Most people have some dissatisfaction or concern about body weight, fatness, or obesity, either personally or professionally. This book shows how the popular understanding of obesity is often at odds with scientific understandings, and how misunderstandings about people with obesity can further contribute to the problem. It describes, in an approachable way, interconnected debates about obesity in public policy, medicine and public health, and how media and social media engage people in everyday life in those debates. In chapters considering body fat and fatness, genetics, metabolism, food and eating, inequality, blame and stigma, and physical activity, this book brings separate domains of obesity research into the field of complexity. By doing so, it aids navigation through the minefield of misunderstandings about body weight, fatness, and obesity that exist today, after decades of mostly failed policies and interventions.
The Theology of Debt in Late Medieval English Literature
Authors: Schuurman Anne
Published: January 2024

Exploring debt's permutations in Middle English texts, Anne Schuurman makes the bold claim that the capitalist spirit has its roots in Christian penitential theology. Her argument challenges the longstanding belief that faith and theological doctrine in the Middle Ages were inimical to the development of market economies, showing that the same idea of debt is in fact intrinsic to both. The double penitential-financial meaning of debt, and the spiritual paradoxes it creates, is a linchpin of scholastic and vernacular theology, and of the imaginative literature of late medieval England. Focusing on the doubleness of debt, this book traces the dynamic by which the Christian ascetic ideal, in its rejection of material profit and wealth acquisition, ends up producing precisely what it condemns. This title is part of the Flip it Open Programme and may also be available Open Access. Check our website Cambridge Core for details.
Classical Hollywood, American Modernism
Authors: Brower Jordan
Published: January 2024

Classical Hollywood, American Modernism charts the entwined trajectories of the Hollywood studio system and literary modernism in the United States. By examining the various ways Hollywood's industry practices inflected the imaginations of authors, filmmakers, and studios, Jordan Brower offers a new understanding of twentieth-century American and ultimately world media culture. Synthesizing archival research with innovative theoretical approaches, this book tells the story of the studio system's genesis, international dominance, decline, and continued symbolic relevance during the American postwar era through the literature it influenced. It examines the American film industry's business practices and social conditions, demonstrating how concepts like anticipated adaptation, corporate authorship, systemic development, and global distribution inflected the form of some of the greatest works of prose fiction and nonfiction by modernist writers, such as Anita Loos, F. Scott Fitzgerald, William Faulkner, Patsy Ruth Miller, Nathanael West, Parker Tyler, Malcolm Lowry, and James Baldwin.

Information provision and preferences for more sustainable dairy farming: Choice experimental evidence from Sweden
Authors: Oyinbo Oyakhilomen , Hansson Helena
Published: January 2024

Dairy farming in Europe faces profound environmental, social, and economic sustainability challenges, which are of significant policy interest. These challenges support the need for a transition toward the uptake of more sustainable dairy farming practices. This paper examines the effects of an advisory instrument “balanced sustainability information” on farmers’ preferences for more grass-based feeding systems using a between-subjects design and a discrete choice experiment among a sample of Swedish dairy farmers. Conceptually, we develop a state-dependent utility framework with Bayesian updating to motivate the impact pathway. Our results demonstrate that on average, balanced sustainability information has negligible effects on farmers’ feed choices, which could be a consequence of opposing responses to the information, among others. Considering farmer heterogeneity based on their identities and prior knowledge, we find support for some evidence of treatment effects. Our findings highlight important and policy-relevant critical reflections about overoptimistic expectations of information provision as an instrument to nudge behavioral change toward more sustainable farming practices.
Fueling SMEs’ product innovation through entrepreneurial passion during COVID-19: The role of dynamic capability and environmental opportunities
Authors: Shi Yongdong , Liu Yu-xiao , Fong Veronica Hoi In , Lan Ya
Published: January 2024

COVID-19 may not only pose threats but also provided opportunities for innovation and growth for many high-tech small- and medium-sized enterprises (SMEs). This study investigates the relationship between entrepreneurial passion (EP), dynamic capability (DC) for innovation and product innovation performance in SMEs during COVID-19. Hierarchical regression and bootstrapping methods were employed per the survey data of 195 Chinese SMEs. The results reveal that EP is an imperative antecedent of DC and product innovation. DC also positively mediates the relationship between SMEs’ product innovation performance and top managers’ EP. In addition, this mediation effect of DC becomes more pronounced when firms are facing more opportunities. These findings advance the existing literature by specifying the process top managers use to cultivate product innovation within SMEs in times of crisis.
FORBIDDEN INDUCED SUBGRAPHS AND THE ŁOŚ–TARSKI THEOREM
Authors: CHEN YIJIA , FLUM JÖRG
Published: January 2024

Let
$\mathscr {C}$
be a class of finite and infinite graphs that is closed under induced subgraphs. The well-known Łoś–Tarski Theorem from classical model theory implies that
$\mathscr {C}$
is definable in first-order logic by a sentence
$\varphi $
if and only if
$\mathscr {C}$
has a finite set of forbidden induced finite subgraphs. This result provides a powerful tool to show nontrivial characterizations of graphs of small vertex cover, of bounded tree-depth, of bounded shrub-depth, etc. in terms of forbidden induced finite subgraphs. Furthermore, by the Completeness Theorem, we can compute from
$\varphi $
the corresponding forbidden induced subgraphs. This machinery fails on finite graphs as shown by our results:

–

There is a class
$\mathscr {C}$
of finite graphs that is definable in first-order logic and closed under induced subgraphs but has no finite set of forbidden induced subgraphs.

–

Even if we only consider classes
$\mathscr {C}$
of finite graphs that can be characterized by a finite set of forbidden induced subgraphs, such a characterization cannot be computed from a first-order sentence
$\varphi $
that defines
$\mathscr {C}$
and the size of the characterization cannot be bounded by
$f(|\varphi |)$
for any computable function f.

Besides their importance in graph theory, the above results also significantly strengthen similar known theorems for arbitrary structures.
The Amazigh Novel, Mythology of Origins, and Return of the Repressed: A Titrological Approach
Authors: Zahir Mohamed
Published: January 2024

Amazigh literature has undergone a veritable historic shift from oral to written form, following the constitutional and institutional recognition of this indigenous language in Morocco and Algeria. We intend to seize this historic moment by focusing on a titrological analysis which, in our view, would be able to highlight the pragmatic side of a stammering literature that would like to proclaim its rebirth and speak to the world. The titular discourse of these novels, still in an experimental phase, informs us about the semiospheres that nourish and irrigate this writing that defossilizes a buried memory, repressed and threatened by the inexorable desymbolization process that traditional cultures are undergoing. This body of work could never be reduced to a simple scription of a narrative folklore that provides it with its cultural semantics; it is driven by the desire to integrate the international literary heritage by dialoguing with it and drawing inspiration from it.
Sample size, range of parameters and time-dependent effects on global sensitivity analysis in sugarcane modelling
Authors: Pereira R. A. A. , Vianna M. S. , Marin F. R.
Published: January 2024

Process-based crop models (PBCM) for sugarcane present many genotype parameters compared to other crops, making it harder to calibrate. Global sensitivity analysis (GSA) has thus become an important tool for understanding, calibrating and further developing PBCMs. This work used a recently updated Agronomic Modular Simulator for Sugarcane (SAMUCA) to simulate crop growth and development, conducted with two treatments: with green cane trash blanket (GCTB) and under bare soil (BARE). Using the extended Fourier Amplitude Sensitivity (eFAST) algorithm, GSA was performed on the 24 genotype parameters of SAMUCA. The objective was to determine the sample size (SZ): how many samplings are necessary to quantify the sensitivity indices. Additionally, we aimed to assess the influence of parameter range variation and identify which genotype parameters explain the highest variance in simulations of the SAMUCA model under BARE and GCTB conditions. The results showed that SZ greatly affected the convergence and sensitivity indices, and the SZ required here needed to be >2049 for the analysis to cover all variables. Two sets of parameter ranges were used for analysis (the first used maximum and integer values of each parameter reported in the literature; the second applied 25% perturbation to the previously calibrated values). The results indicated that the parameter range affected the parameters' order of importance. Furthermore, we identified that at different phenological stages of sugarcane development, distinct parameters were responsible for explaining the most variance of the output. However, there was no difference among ratoons or interference in the results of BARE or GCTB.
Centrality statistics of symptom networks of schizophrenia: a systematic review
Authors: Buchwald Khan , Narayanan Ajit , Siegert Richard John , Vignes Matthieu , Arrowsmith Kim , Sandham Margaret
Published: January 2024

The network theory of psychological disorders posits that systems of symptoms cause, or are associated with, the expression of other symptoms. Substantial literature on symptom networks has been published to date, although no systematic review has been conducted exclusively on symptom networks of schizophrenia, schizoaffective disorder, and schizophreniform (people diagnosed with schizophrenia; PDS). This study aims to compare statistics of the symptom network publications on PDS in the last 21 years and identify congruences and discrepancies in the literature. More specifically, we will focus on centrality statistics. Thirty-two studies met the inclusion criteria. The results suggest that cognition, and social, and occupational functioning are central to the network of symptoms. Positive symptoms, particularly delusions were central among participants in many studies that did not include cognitive assessment. Nodes representing cognition were most central in those studies that did. Nodes representing negative symptoms were not as central as items measuring positive symptoms. Some studies that included measures of mood and affect found items or subscales measuring depression were central nodes in the networks. Cognition, and social, and occupational functioning appear to be core symptoms of schizophrenia as they are more central in the networks, compared to variables assessing positive symptoms. This seems consistent despite heterogeneity in the design of the studies.
Abnormal intrinsic brain functional network dynamics in first-episode drug-naïve adolescent major depressive disorder
Authors: Wu Baolin , Long Xipeng , Cao Yuan , Xie Hongsheng , Wang Xiuli , Roberts Neil , Gong Qiyong , Jia Zhiyun
Published: January 2024

Background

Alterations in brain functional connectivity (FC) have been frequently reported in adolescent major depressive disorder (MDD). However, there are few studies of dynamic FC analysis, which can provide information about fluctuations in neural activity related to cognition and behavior. The goal of the present study was therefore to investigate the dynamic aspects of FC in adolescent MDD patients.

Methods

Resting-state functional magnetic resonance imaging data were acquired from 94 adolescents with MDD and 78 healthy controls. Independent component analysis, a sliding-window approach, and graph-theory methods were used to investigate the potential differences in dynamic FC properties between the adolescent MDD patients and controls.

Results

Three main FC states were identified, State 1 which was predominant, and State 2 and State 3 which occurred less frequently. Adolescent MDD patients spent significantly more time in the weakly-connected and relatively highly-modularized State 1, spent significantly less time in the strongly-connected and low-modularized State 2, and had significantly higher variability of both global and local efficiency, compared to the controls. Classification of patients with adolescent MDD was most readily performed based on State 1 which exhibited disrupted intra- and inter-network FC involving multiple functional networks.

Conclusions

Our study suggests local segregation and global integration impairments and segregation-integration imbalance of functional networks in adolescent MDD patients from the perspectives of dynamic FC. These findings may provide new insights into the neurobiology of adolescent MDD.
ShakingBot: dynamic manipulation for bagging
Authors: Gu Ningquan , Zhang Zhizhong , He Ruhan , Yu Lianqing
Published: January 2024

Bag manipulation through robots is complex and challenging due to the deformability of the bag. Based on the dynamic manipulation strategy, we propose a new framework, ShakingBot, for the bagging tasks. ShakingBot utilizes a perception module to identify the key region of the plastic bag from arbitrary initial configurations. According to the segmentation, ShakingBot iteratively executes a novel set of actions, including Bag Adjustment, Dual-arm Shaking, and One-arm Holding, to open the bag. The dynamic action, Dual-arm Shaking, can effectively open the bag without the need to take into account the crumpled configuration. Then, the robot inserts the items and lifts the bag for transport. We perform our method on a dual-arm robot and achieve a success rate of 21/33 for inserting at least one item across various initial bag configurations. In this work, we demonstrate the performance of dynamic shaking action compared to the quasi-static manipulation in the bagging task. We also show that our method generalizes to variations despite the bag’s size, pattern, and color. Supplementary material is available at https://github.com/zhangxiaozhier/ShakingBot.
Kinematics inverse solution of assembly robot based on improved particle swarm optimization
Authors: Zhang Shixiong , Li Ang , Ren Jianxin , Ren Ruilong
Published: January 2024

Inverse kinematics of robot is the basis of robot assembly, which directly determines the pose of robot. Because the traditional inverse solution algorithm is limited by the robot topology structure, singular pose and inverse solution accuracy, it affects the use of robots. In order to solve the above problems, an improved particle swarm optimization (PSO) algorithm is proposed to solve the inverse problem of robot. This algorithm initializes the particle population based on joint angle limitations, accelerating the convergence speed of the algorithm. In order to avoid falling into local optima and premature convergence, we have proposed a nonlinear weight strategy to update the speed and position of particles, enhancing the algorithm’s search ability, in addition introducing a penalty function to eliminate particles exceeding joint limits. Finally, the positions of common points and singular points are selected on PUMA 560 robot and redundant robot for inverse kinematics simulation verification. The results show that, compared with other algorithms, the improved PSO algorithm has higher convergence accuracy and better convergence speed in solving the inverse solution, and the algorithm has certain universality, which provides a new solution for the inverse kinematics solution of the assembly robot.
Cultural history: an interdisciplinary approach
Authors: Burke Peter
Published: January 2024

This article concentrates on what historians have borrowed and adapted from neighbouring disciplines in the last few decades, rather than what they have lent (much more rarely). It discusses the ‘social turn’ of the 1960s, the movements for historical anthropology and ‘psychohistory (drawing on psychoanalysis) in the 1970s, the literary turn of the 1980s (ranging from the poetics of history to the analysis of ‘fiction in the archives’), the history of ‘social’ or ‘cultural’ memory, the rise of the history of gender, and the ‘cultural turn’ of the 1990s. In those forty years, historians were often in dialogue with social scientists and with other scholars in the humanities. In the 21st century, by contrast, there has been a rapprochement with experimental psychology and neuroscience (in the case of studies of memory and emotion) and with biology, culminating – so far – in a ‘bio-history’ concerned with the co-evolution of humans and animals. The famous opposition between ‘nature’ and ‘culture’ is melting away.

Published: January 2024

There is limited evidence on heterogenous co-developmental trajectories of internalizing (INT) and externalizing (EXT) problems from childhood to adolescence and predictors of these joint trajectories. We utilized longitudinal data from Raine Study participants (n = 2393) to identify these joint trajectories from 5 to 17 years using parallel-process latent class growth analysis and analyze childhood individual and family risk factors predicting these joint trajectories using multinomial logistic regression. Five trajectory classes were identified: Low-problems (Low-INT/Low-EXT, 29%), Moderate Externalizing (Moderate-EXT/Low-INT, 26.5%), Primary Internalizing (Moderate High-INT/Low-EXT, 17.5%), Co-occurring (High-INT/High-EXT, 17%), High Co-occurring (Very High-EXT/High-INT, 10%). Children classified in Co-occurring and High Co-occurring trajectories (27% of the sample) exhibited clinically meaningful co-occurring problem behaviors and experienced more adverse childhood risk-factors than other three trajectories. Compared with Low-problems: parental marital problems, low family income, and absent father predicted Co-occurring and High Co-occurring trajectories; maternal mental health problems commonly predicted Primary Internalizing, Co-occurring, and High Co-occurring trajectories; male sex and parental tobacco-smoking uniquely predicted High Co-occurring membership; other substance smoking uniquely predicted Co-occurring membership; speech difficulty uniquely predicted Primary Internalizing membership; child’s temper-tantrums predicted all four trajectories, with increased odds ratios for High Co-occurring (OR = 8.95) and Co-occurring (OR = 6.07). Finding two co-occurring trajectories emphasizes the importance of early childhood interventions addressing comorbidity.
Pathways from adolescent close friendship struggles to adult negative affectivity
Authors: Allen Joseph P. , Costello Meghan A. , Hellwig Amanda F. , Stern Jessica A.
Published: January 2024

This 19-year prospective study applied a social development lens to the challenge of identifying long-term predictors of adult negative affectivity. A diverse community sample of 169 individuals was repeatedly assessed from age 13 to age 32 using self-, parent-, and peer-reports. As hypothesized, lack of competence establishing and maintaining close friendships in adolescence had a substantial long-term predictive relation to negative affectivity at ages 27–32, even after accounting for prior depressive, anxious, and externalizing symptoms. Predictions also remained robust after accounting for concurrent levels of depressive symptoms, indicating that findings were not simply an artifact of previously established links between relationship quality and depressive symptoms. Predictions also emerged from poor peer relationships within young adulthood to future relative increases in negative affectivity by ages 27–32. Implications for early identification of risk as well as for potential preventive interventions are discussed.

Published: January 2024

Exploring the nutritional potential of underutilized legumes such as Dolichos bean (Lablab purpureus L.) is of great significance, particularly, in view of accomplishing the United Nation's Sustainable Development Goal number two, which emphasizes on improving food and nutrition security by 2030. A thorough understanding of genetic variability is crucial for developing biofortified cultivars of Dolichos bean. In this study, the Dolichos bean genotypes represented by pole and bush types (28 bush and 19 pole types) were assessed for genetic variability for Cu, Mn, Fe and Zn contents. Pole type genotypes had higher average contents for all micronutrients except manganese. Among micronutrients, Cu, Fe, Mn and Zn, content ranged from 10.10–19.95, 77.13–331.93, 22.78–46.40 and 42.03–102.85 mg kg−1 in pole type, and 8.2–18.5, 50.8–99.3, 25.65–53.25 and 37.15–63.25 mg kg−1 in bush type beans, respectively. Strong positive correlations between Cu, Fe and Zn concentrations occurred, which indicates the possibility of simultaneous improvement of these nutrients. Pod pigmentation was positively correlated with contents of Fe and Zn. There was an association of micronutrients with yield.

Abstract: Most research on depressive rumination is generally related to performance deterioration. Rumination, however, may be adaptive if it is associated with reflection, improving task performance. The mechanisms responsible for improved task performance related to rumination are not well-known. Thus, this study investigated the role of effort in understanding how people, high on reflection, engage in task performance. We argue that high reflectors would be more sensitive to “effort congruent” cues than low reflectors and would, therefore, take that extra step to invest more effort, which would then be translated into improved task performance. We manipulated motivational states of effort investment (effort enhancing vs. effort minimizing) and tested the effect of individual differences in reflection on the performance of the multiple-goal task. Results showed that high reflectors (vs. low) performed better when asked to focus on tasks requiring more effort. These new insights make a meaningful contribution to the dual model theory of rumination.
Accurate Magnitude and Stress Drop Using the Spectral Ratios Method Applied to Distributed Acoustic Sensing
Authors: Lior Itzhak
Published: January 2024

The reliable estimation of earthquake magnitude and stress drop are key in seismology. The novel technology of distributed acoustic sensing (DAS) holds great promise for source parameter inversion owing to the measurements' high spatial density. In this study, I demonstrate the robustness of DAS for magnitude and stress drop estimation using the empirical Green's function deconvolution method. This method is applied to nine co‐located earthquakes recorded in Israel following the 2023 Turkey earthquakes. Spectral ratios were stacked along the fiber, and fitted with a relative Boatwright source spectral model. Excellent fits were obtained even for similar sized earthquakes. Stable seismic moments and stress drops were calculated assuming that the moment of one earthquake is known. DAS derived estimates were found to be more stable and reliable than those obtained using a dense accelerometer network. The results demonstrate the great potential of DAS for source studies.

Numerical modeling of ice sheet motion and hence projections of global sea level rise require information about the evolving subglacial environment, which unfortunately remains largely unknown due to its difficulty of access. Here we advance such subglacial observations by reporting multi‐year observations of seismic tremor likely associated with glacier sliding at Helheim Glacier. This association is confirmed by correlation analysis between tremor power and multiple environmental forcings on different timescales. Variations of the observed tremor power indicate that different factors affect glacial sliding on different timescales. Effective pressure may control glacial sliding on long (seasonal/annual) timescales, while tidal forcing modulates the sliding rate and tremor power on short (hourly/daily) timescales. Polarization results suggest that the tremor source comes from an upstream subglacial ridge. This observation provides insights on how different factors should be included in ice sheet modeling and how their timescales of variability play an essential role.

Using the Arase and Van Allen Probes satellite observations, we investigate the nonlinear electromagnetic ion cyclotron (EMIC) rising‐tone (RT) emissions with an increase of the solar wind dynamic pressure in the dayside magnetosphere. We find that EMIC RT emissions are accompanied by the extended dayside uniform zone (DUZ) over |MLAT| < 25° due to the dayside magnetospheric compression by an increase in Pdyn. Using the observed plasma and magnetic field data, we modeled the threshold amplitude for the nonlinear EMIC waves and compared it with the observation. The small gradient of the ambient magnetic field strongly contributes to the reduction in the threshold amplitude of nonlinear wave growth compared to other parameters. When the threshold amplitude falls to comparable level of pre‐existing EMIC waves, EMIC RT emissions are immediately triggered, suggesting direct evidence that the DUZ is the preferred condition to cause the nonlinear EMIC RT emission in the dayside magnetosphere.

High‐precision measurements of the magnetic field are critical to explore the near‐Mars environment. The Mars Orbiter MAGnetometer (MOMAG) is one of seven payloads on board the Tianwen‐1 orbiter. Its zero offset needs regular calibration, and the Wang‐Pan method I is applied to the MOMAG when the Tianwen‐1 orbiter is in the solar wind. The orbiter will remain out of the solar wind over tens of days each year, a method is necessary to ensure the accuracy of the zero offset during this period. Recently, a new method was proposed by Wang (2022b), https://doi.org/10.3847/1538-4357/ac822c, which is referred to as the Wang method II for ease of description. Here, we test the performance of this method using the MOMAG data measured in the Martian magnetosheath. We find that the zero offset Ow determined by the Wang method II varies around the zero offset Owp calculated by the Wang‐Pan method I using the potential Alfvénic fluctuations in the solar wind. After smoothing with a temporal window of 27 days, Ow is able to achieve an accuracy close to Owp. If the data segment has no gaps and its duration is < 27 days, the smoothed Ow might have an error >2 nT, but the error tends to be smaller if the segment's duration is longer. Our tests suggest that the Wang method II is suitable for the in‐flight calibration of the MOMAG when the Tianwen‐1 orbiter remains out of the solar wind.

Observations from the Michelson Interferometer for Global High‐Resolution Thermospheric Imaging onboard the Ionospheric Connection Explorer spacecraft are used to study the response of OI630.0 and OI557.7 nm dayglow to a moderate geomagnetic storm on 27 August 2021. The storm reaches a minimum Dst index of −82 nT, significantly impacting the dayglow within the latitudinal range of approximately 20°N–42°N, where the dayglow observations are of good quality. During the geomagnetic storm, the OI630.0 dayglow intensity slightly increases, while the peak volume emission rate (VER) decreases, and the peak height rises noticeably. The F‐layer intensity, peak VER, and the entire‐layer intensity of OI557.7 dayglow decrease significantly. The rise in peak height is not noticeable for the OI557.7 dayglow. The VERs of the both dayglow emissions respond differently to the geomagnetic storm at different altitudes. The OI630.0 dayglow layer as a whole extends upward and rises in altitude. For dayglow averaged above 35°N, the OI630.0 dayglow VER increases above approximately 225 km but decreases below this altitude. The largest increase occurs near 300 km, reaching approximately 82.8%, while the largest decrease occurs around 160 km, reaching about −22.0%. The OI630.0 dayglow intensity increases by approximately 6.3%, the peak VER decreases by about −8.0%, and the peak height rises by approximately 16.3 km, corresponding to a 7.8% increase. The F‐layer intensity, peak VER, and the entire‐layer intensity of OI557.7 dayglow decrease by approximately −27.5%, −32.4% and −17.4%, respectively. The response of the dayglow also depends on longitude and is accompanied by a southward meridional wind.
