Reactivation-dependent transfer of fear memory between contexts requires M1 muscarinic receptor stimulation in dorsal hippocampus of male rats
Authors: Abouelnaga Karim H. , Huff Andrew E. , Jardine Kristen H. , O'Neill Olivia S. , Winters Boyer D.
Published: October 2024

Memory updating is essential for integrating new information into existing representations. However, this process could become maladaptive in conditions like post-traumatic stress disorder (PTSD), when fear memories generalize to neutral contexts. Previously, we have shown that contextual fear memory malleability in rats requires activation of M1 muscarinic acetylcholine receptors in the dorsal hippocampus. Here, we investigated the involvement of this mechanism in the transfer of contextual fear memories to other contexts using a novel fear memory updating paradigm. Following brief reexposure to a previously fear conditioned context, male rats (n= 8–10/group) were placed into a neutral context to evaluate the transfer of fear memory. We also infused the selective M1 receptor antagonist pirenzepine into the dorsal hippocampus before memory reactivation to try to block this effect. Results support the hypothesis that fear memory can be updated with novel contextual information, but only if rats are reexposed to the originally trained context relatively recently before the neutral context; evidence for transfer was not seen if the fear memory reactivation was omitted or if it occurred 6 h before neutral context exposure. The transferred fear persisted for 4 weeks, and the effect was blocked by M1 antagonism. These findings strongly suggest that fear transfer requires reactivation and destabilization of the original fear memory. The novel preclinical model introduced here, and its implication of muscarinic receptors in this process, could therefore inform therapeutic strategies for PTSD and similar conditions.

Excited states of the molybdenum isotopes Mo4297,99,101 have been populated in two experiments which used fusion-fission and binary grazing reactions to populate yrast states of the nuclei of interest. In the first experiment, the GASP array of escape-suppressed Ge detectors was used to detect γ rays from fusion-fission products initiated by the interaction of a 230-MeV beam of S36 ions with a thick target of

. In the multinucleon transfer experiment, a 530-MeV beam of Zr96 ions was incident on a thin Sn124 target; projectile-like ejectiles were detected and identified using the PRISMA magnetic spectrometer and their associated γ rays were detected using the CLARA array of escape-suppressed Ge detectors. In Mo99, the previously known positive-parity νd5/2 decay sequence was extended to spin (25/2+) while, in Mo101, a similar, but hitherto unobserved νg7/2 positive-parity decay sequence was established to spin (27/2+). In Mo99 and in Mo101, previously observed νh11/2 negative-parity decay sequences were also observed to spin 27/2−. Although the observed decay sequences in Mo97 have not been extended beyond the results of earlier work, a disagreement in the published level structure of the h11/2 band has been resolved. The observed positive-parity decay sequences have been compared with the results of state-of-the-art shell-model calculations; the general features of the energy spectrum of excited states of Mo97, Mo99, and Mo101 are reproduced, but not in detail. The experimental energies of the negative-parity states of Mo99 and Mo101 are reasonably well reproduced in particle-rotor (PRM) calculations. For Mo97, better agreement with the high-spin states was obtained when the core in the PRM calculations was treated in a variable moment of inertia approach. For the νh11/2 negative-parity decay sequences of the three isotopes studied here, model-dependent evidence is presented for nuclear shape changes with increasing neutron number.

Transverse-momentum dependent model for hadronization in deep-inelastic lepton-nucleus scattering off heavy nuclei
Authors: Ceccopieri F. A. , Dupré R.
Published: October 2024

Semi-inclusive deep inelastic scattering off nuclei is a unique process to study the parton propagation mechanism and its modification induced by the presence of the nuclear medium. It allows us to probe the medium properties, particularly the cold nuclear matter transport coefficient, which can be directly linked to the nuclear gluon density. We present here a model for hadron production in deep inelastic lepton-nucleus scattering, which takes into account the hadronic transverse momentum of final state particles via transverse-momentum dependent parton distributions and fragmentation functions. We implement parton energy loss and hadronic absorption with a geometrical model of the nucleus. The model is compared with the nuclear semi-inclusive deep-inelastic scattering multiplicity ratios and transverse-momentum broadening data from the CLAS, HERMES, and EMC collaborations, aiming for a simultaneous description of these data sets. We obtain a good agreement over the various nuclear targets and the wide kinematical range of those experiments. We best describe the data with a transport coefficient q̂=0.3GeV/fm2, and we highlight the importance and the role of correlations in extracting this quantity.

Impact of gauge fixing precision on the continuum limit of nonlocal quark-bilinear lattice operators
Authors: Zhang Kuan , Huo Yi-Kai , Ji Xiangdong , Schäfer Andreas , Shi Chun-Jiang , Sun Peng , Wang Wei , Yang Yi-Bo , Zhang Jian-Hui ,   Lattice Parton Collaboration
Published: October 2024

We analyze the gauge fixing precision dependence of some nonlocal quark-bilinear lattice operators interesting in computing parton physics for several measurements, using five lattice spacings ranging from 0.032 to 0.121 fm. Our results show that gauge-dependent nonlocal measurements are significantly more sensitive to the precision of gauge fixing than anticipated. The impact of imprecise gauge fixing is significant for fine lattices and long distances. For instance, even with the typically defined precision of Landau gauge fixing of 10−8, the deviation caused by imprecise gauge fixing can reach 12%, when calculating the trace of Wilson lines at 1.2 fm with a lattice spacing of approximately 0.03 fm. Similar behavior has been observed in ξ gauge and Coulomb gauge as well. For both quasi-parton-distribution functions (quasi-PDFs) and quasi-transverse-momentum-dependent PDFs operators renormalized using the regularization independent momentum subtraction (RI/MOM) scheme, convergence for different lattice spacings at long distance is only observed when the precision of Landau gauge fixing is sufficiently high. To describe these findings quantitatively, we propose an empirical formula to estimate the required precision.

Loop corrections versus marginal deformations in celestial holography
Authors: He Song , Mao Pujian , Mao Xin-Cheng
Published: October 2024

Four-dimensional all-loop amplitudes in quantum electrodynamics and gravity exhibit universal IR singularities with a factorization structure. This structure is governed by tree amplitudes and a universal IR-divergent factor representing the exchange of soft particles between external lines. This Letter offers a precise dual interpretation of these universal IR-divergent factors within celestial holography. Considering the tree amplitude as the foundation of the celestial conformal field theory (CCFT), these universal factors correspond to marginal deformations with a construction in the CCFT. Remarkably, a novel geometric representation of these deformations through topological gauging provides an exact description of transitions within bulk vacuum moduli spaces which extends the celestial holography beyond the perturbative level. Our findings establish a concrete dictionary for celestial holography and offer a holographic lens to understand loop corrections in scattering amplitudes.

study of highly tunable charge transfer in
β−RuCl3
/graphene heterostructures
Authors: Razpopov Aleksandar , Valentí Roser
Published: October 2024

Heterostructures of graphene in proximity to magnetic insulators open the possibility to investigate exotic states emerging from the interplay of magnetism, strain and charge transfer between the layers. Recent reports on the growth of self-integrated atomic wires of β−RuCl3 on graphite suggest these materials as versatile candidates to investigate these effects. Here we present detailed first-principles calculations on the charge transfer and electronic structure of β−RuCl3/graphene heterostructures and provide a comparison with the work function analysis of the related honeycomb family members α−RuX3 (X = Cl,Br,I). We find that proximity of the two layers leads to a hole-doped graphene and electron-doped RuX3 in all cases, which is sensitively dependent on the distance between the two layers. Furthermore, strain effects due to lattice mismatch control the magnetization which itself has a strong effect on the charge transfer. Charge accumulation in β−RuCl3 strongly drops away from the chain making such heterostructures suitable candidates for sharp interfacial junctions in graphene-based devices.

X-ray crystal structure of proliferating cell nuclear antigen 1 from Aeropyrum pernix
Authors: Yamauchi Takahiro , Kikuchi Makiko , Iizuka Yasuhito , Tsunoda Masaru
Published: October 2024

Proliferating cell nuclear antigen (PCNA) plays a critical role in DNA replication by enhancing the activity of various proteins involved in replication. In this study, the crystal structure of ApePCNA1, one of three PCNAs from the thermophilic archaeon Aeropyrum pernix, was elucidated. ApePCNA1 was cloned and expressed in Escherichia coli and the protein was purified and crystallized. The resulting crystal structure determined at 2.00 Å resolution revealed that ApePCNA1 does not form a trimeric ring, unlike PCNAs from other domains of life. It has unique structural features, including a long interdomain-connecting loop and a PIP-box-like sequence at the N-terminus, indicating potential interactions with other proteins. These findings provide insights into the functional mechanisms of PCNAs in archaea and their evolutionary conservation across different domains of life. A modified medium and protocol were used to express recombinant protein containing the lac operon. The expression of the target protein increased and the total incubation time decreased when using this system compared with those of previous expression protocols.
The value of statistical life in air and road transport
Authors: Milovanović Milica , Čokorilo Olja , Ivković Ivan , Stojiljković Branimir , Vasov Ljubiša
Published: October 2024

Purpose

Accidents occur in all transport modes and can cause significant material damage and loss of life. To efficiently allocate resources that enable the reduction of accidents, it is necessary to estimate the value of a statistical life (VSL). This study aims to show how the statistical value of human life in air and road traffic is determined.

Design/methodology/approach

This study examines and applies recent empirical evidence aimed at clarifying the basic concept of the VSL and defining the reasons for its importance in evaluating public policies in aviation safety and road traffic safety. The research focuses on the principal equity indicators, both theoretical and empirical, that must be confronted to provide a credible estimate of the VSL.

Findings

Previous research shows that the VSL could have a considerable range of possible values. This study emphasizes that risk reduction funds need to be distributed in a consistent and equitable manner to achieve the best outcomes for society as a whole.

Practical implications

This research will guide future research efforts towards understanding the impact of the estimated statistical life value on air and road safety implications.

Social implications

This study strengthens awareness of the importance of the VSL in evaluating public policies in the field of aviation and road safety.

Originality/value

To the best of the authors’ knowledge, this study is one of the first to compare air and road traffic from the perspective of the VSL evaluation.
Thinking or feeling? The effect of information diversity on consumption decisions based on the social support framework
Authors: Dong Xiaosong , Li Weixin
Published: October 2024

Purpose

Instrumental and emotional information influence paradoxically on people’s decision-making, and similar influences are more evident in e-commerce scenarios where physical information is limited. This study aims to construct a systematic explanatory framework for the influence of multidimensional recommendation information diversity (RID) on users' click and purchase decisions based on the social support theory (SST).

Design/methodology/approach

This study analyses 453,176 data from 67,079 users of a Chinese e-commerce platform, applying lasso algorithmic techniques and cross-fit partialling-out (XPO) regression for empirical analysis.

Findings

The study finds that instrumental support information diversity (ISID) and emotional support information diversity (ESID) play divergent roles, and that the effects of both on user decision-making are inconsistent with mode-flip and marginal change. Differences in users' information craving and information overload processing mechanisms for instrumental and emotional information, leading to an inverted U-shaped effect of ISID on consumption decisions, while ESID has a U-shaped effect. Additionally, supplier certification eliminates the marginal change in ESID, and products with a high information standardisation degree eliminate the marginal change in ISID.

Originality/value

Research results reveal the opposing roles of the two types of RID and the application boundaries of their roles, providing empirical evidence for academic research.
Is there a danger of making customers feel too empowered? Exploring the double-edged sword of customer orientation and creative benefits
Authors: Liu Yeyi , Mayerhofer Tobias Johannes Hubert , Marchand André , Foscht Thomas , Fritze Martin Paul , Eisingerich Andreas Benedikt
Published: October 2024

Purpose

This study aims to explore the extent to which customer orientation and creative benefits offered by a firm may weaken rather than strengthen customer engagement. In doing so, it sheds new light on how customer orientation and creative benefits may facilitate rather than hinder engagement by customers.

Design/methodology/approach

A field study provides a test of the proposed effects in a hedonic consumption setting with 1,703 customers of an online dating service. Furthermore, an experimental study with 277 executives in a functional consumption setting (new mobile app) helps affirm the robustness of the field study findings.

Findings

This research theorizes and examines how communal relationship norms between customers and a firm, along with customers’ psychological empowerment, mediate the effect of customer orientation and creative benefits on customer engagement. A provocative finding of the study is that communal relationship norms help boost, whereas psychological empowerment reduces, the effects of both customer orientation and creative benefits on customer engagement.

Research limitations/implications

The research examines different relationship norms and how they can become integral to customer–company relationships; this perspective helps reveal the underlying dynamics. It contributes to the literature on customer engagement by theorizing and demonstrating the link between customer orientation and customer engagement, two central constructs in the marketing literature. It theorizes and demonstrates that providing creative benefits brings about a direct competitive advantage for the product itself, and acts as a significant variable that explains the company−customer relationship.

Practical implications

The findings highlight the advantages and challenges associated with encouraging customer engagement. First, they suggest that companies emphasize their customer orientation and creative benefits. Second, managers should try to minimize the possible process of raising customers’ psychological empowerment while maximizing the impact of communal relationship norms.

Originality/value

This study identifies psychological empowerment as a key reason customer-oriented companies that provide creative benefits still struggle to engage their customers. It also suggests viable tactics to overcome barriers to enhanced customer engagement, such as by minimizing the effects of customers’ psychological empowerment while maximizing the impact of their perceived communal relationship norms.

Findings

The study reveals a strong connection between knowledge sharing and its positive influence on employee job engagement and the perception of meaningful work, both of which play essential mediating roles in promoting organizational sustainability. The findings emphasize the critical importance of knowledge sharing in driving sustainability efforts, showing how the interplay between job engagement and meaningful work significantly enhances these outcomes.

Originality/value

This research contributes to social exchange theory by demonstrating the dual mediating roles of job engagement and meaningful work between knowledge sharing and sustainability.
Leveraging event portfolios for strategic business development: a case study of Singapore Changi Airport
Authors: Chutiphongdech Thanavutd , Phengkona Jutamas
Published: October 2024

Purpose

This research article examines event marketing in the airport business, specifically how an airport leverages event portfolios to develop its businesses by marketing itself as a destination, improving the user experience and generating revenue outside of aviation-related activities. Focusing on Singapore Changi Airport as a case study, the research underscores the airport’s business development in a competitive environment.

Design/methodology/approach

The study employs thematic data analysis to examine how Changi Airport leverages an event portfolio as a strategic business development tool. It conducts documentary research by gathering a diverse range of grey literature sources from the online public domain. These sources include documents related to airports, online news and media portals and user-generated content on social media platforms. The analysis is conducted in an inductive manner.

Findings

Singapore Changi Airport has recently leveraged events as a strategic marketing strategy for developing nonaeronautical business operations. As an attraction to appeal to tourists, the airport organised multiple types of events in its portfolio. Furthermore, the airport offers a wide range of event-related activities within its premises, including both sporting and cultural events. The purpose of these activities is to actively engage visitors and air travellers by offering a range of interactive experiences, including games and challenges. Such event-related activities reflect the airport’s transformation into a lifestyle platform.

Originality/value

Critics commonly highlight the lack of empirical research and the restricted relevance of the findings in event and festival research. This article consolidates the existing knowledge on airport management and event business to enhance the event marketing and event portfolio literature, specifically in the setting of airport business.
Supply chain risk management for humanitarian aid delivery: risk identification and contingency analysis
Authors: Löffel Maximilian , Schmidt Christoph G. , Wagner Stephan M.
Published: October 2024

Purpose

Humanitarian organizations are responsible for delivering aid under diverse circumstances in various contexts. We argue that humanitarian organizations face specific challenges in their logistics and operations. Thus, adequate supply chain risk management is required to facilitate effective and efficient humanitarian aid delivery.

Design/methodology/approach

We first identify potential supply chain risks in humanitarian aid delivery from the literature. We then utilize an expert survey to determine the probability and impact ratings of the identified risks, assessing the importance of six aggregated risk categories. To examine the influence of contingencies on a country, organization, and crisis level, we investigate the effect of ten contextual factors on the importance of different supply chain risks in humanitarian aid delivery.

Findings

We derive six relevant risk categories for humanitarian aid delivery and develop five propositions concerning criticality, context-sensitivity, relevant contingencies, and risk management approaches. Findings and propositions encourage and guide future research on the topic.

Practical implications

Risk identification and assessment support mission-specific decision-making. Our findings encourage and foster organizational learning between missions. A differentiated view of risk types allows for stronger inter-organizational collaboration within the sector and beyond.

Originality/value

This study is among the first to derive supply chain risks and categories specific to humanitarian aid delivery. Contingency analysis on a country, organization, and crisis level offers unique insights into risk management in humanitarian aid delivery.
Towards more accessible digital urban public transport for people with autism spectrum disorder (ASD): a critical incident analysis (CIT)
Authors: Cerdan-Chiscano Monica
Published: October 2024

Purpose

This study empirically and comparatively examines two digital technologies that have been implemented as part of the experience of urban public transport during the COVID-19 pandemic in the city of Barcelona, the digitization of tickets and self-service technology in kiosks in the different operators of the metropolitan transport authority (ATM) environment. The study gives a voice to people with ASD and makes a theoretical and practical contribution to making urban transport increasingly digitized after the COVID-19 pandemic, more accessible and inclusive for the group, little observed so far.

Design/methodology/approach

The data collection consisted of a discussion group, ethnographic techniques and a visit to the Barcelona Metro (2022), and interviews after the visit through a semi-structured questionnaire with 12 participants with ASD. This study uses the critical incident analysis (CIT).

Findings

Results provide an extension of the attribute-based Dabholkar model (1996) that applies to the perception of the use of self-service technology, when using digital technologies in urban transport.

Originality/value

This redefinition of the current model of the perception of the use of technology, taking into account the needs of people with ASD, will enable better decision making by transport operators for previously neglected groups.

A topic that still requires a lot of work before hitting mainstream approaches to destination development, even though it should have been on the policy agendas for many years already.
Self-leadership practices and beliefs in nonprofit organizations: differences between leaders and non-leaders
Authors: Dunaetz David R. , Gobrail Mark , Howard Jaye , Lord Jasmine , Yun Jaimie C.
Published: October 2024

Purpose

Self-leadership theory predicts that specific self-leadership practices will enable individuals to better accomplish their goals. However, little is known about the role that these practices play in conventional leadership (leading or influencing others). This study compares leaders to non-leaders (N = 318) in nonprofits and examines both the extent to which self-leadership practices are employed and the strength of beliefs concerning their importance.

Design/methodology/approach

Online survey of two groups: leaders and non-leaders of nonprofit organizations.

Findings

Leaders practiced self-goal setting (d = 0.47) and self-observation (d = 0.45) more than non-leaders. Non-leaders practiced more self-reward (d = 0.33) and self-punishment (d = 0.37) than leaders. The only differences in belief concerning the importance of the self-leadership practices were due to leaders believing self-goal setting (d = 0.46) and self-observation (d = 0.36) were more important than non-leaders did.

Research limitations/implications

If self-leadership practices contribute to leadership effectiveness or emergence, this study indicates that goal setting and self-observation (monitoring progress toward goals) may contribute positively to the leadership of others, whereas self-reward and self-punishment may contribute negatively.

Practical implications

Self-leadership may not be as important to the leadership of others as is often claimed or implied.

Originality/value

This is the first study to look at how self-leadership practices differ between leaders and non-leaders.

Authors: García-Sánchez Isabel-María , Aibar-Guzmán Beatriz , Raimo Nicola , Vitolla Filippo
Published: October 2024

Purpose

The 2030 Agenda represents a unique and historic opportunity to achieve sustainable development by establishing high-priority issues to be addressed, such as the eradication of extreme poverty, the reduction of inequalities, and inclusive economic growth with decent work for all. This study aims to analyze the commitment of the world’s leading companies to the sustainable development goals (SDGs) set out in this roadmap.

Design/methodology/approach

To provide a dynamic and global view of corporate commitment to the 2030 Agenda, the authors identified the 3,910 companies that have reported on various initiatives related to the SDGs over the period 2019–2022 (15,640 observations), based on the Refinitiv database. The companies that make up the sample are located in 71 countries across eight geographic regions.

Findings

The results show a positive evolution in the actions and initiatives that companies are developing to contribute to the protection of people, the planet, prosperity, universal peace, and access to justice. However, there are differences between regions and countries and between the 17 objectives.

Originality/value

The authors’ approach allows for a detailed understanding of business preferences, how these sustainable business practices contribute to achieving the SDGs in different regions and what contextual factors influence this contribution. In this sense, the analysis of the regional distribution of corporate commitments to the SDGs provides valuable information on the priority areas of focus in different regions of the world.
Green skepticism: review and research agenda
Authors: Sivapalan Achchuthan , Jebarajakirthy Charles , Saha Raiswa , Mehta Pooja , Balaji M.S. , Maseeh Haroon Iqbal
Published: October 2024

Purpose

Despite a growing interest in investigating green skepticism, there has been a paucity of effort in synthesizing green skepticism research. This study aims to synthesize extant green skepticism research. This study is useful in providing a comprehensive synthesis of research on green skepticism and identifying key gaps in the existing literature, thereby paving the way for future research directions. This research demonstrates a comprehensive understanding of the dominant theories, contexts (i.e. countries), characteristics (i.e. key variables and their associations) and methods (i.e. research design) employed in green skepticism research.

Design/methodology/approach

A hybrid review method that combined an Systematic Literature Review (SLR) with lexicometric analysis was employed to present a comprehensive synthesis of the green skepticism literature.

Findings

The findings showed that many theories have been applied to green skepticism research with the theory of planned behavior and attribution theory being prominently used. The review also proposes a conceptual framework that illustrates the relationships between antecedents and consequences reported in the green skepticism literature. Lexicometric analysis identified six major themes in green skepticism research, including trust in green products, product-related attributes, environmental attributes, social responsibility, organic consumption and promotional campaigns.

Research limitations/implications

This review included only papers authored in English. Consequently, studies conducted in other languages were not taken into account. Future research could broaden the understanding of green skepticism by incorporating studies conducted in different languages.

Practical implications

This study provides practical implications for retailers, marketers and policymakers to combat green skepticism and encourage the purchase of green items. This study suggests integrating endorsements from authorized third-party organizations or celebrities into green marketing campaigns to reduce skepticism. Further, aligning corporate social responsibility efforts with genuine social welfare goals can build consumer trust. Finally, securing third-party endorsements for ecological claims will emphasize product credibility and drive green purchase intention.

Originality/value

To the authors’ knowledge, this study represents the first attempt to review the extant literature in green skepticism by integrating a systematic review approach, lexicometric analysis and the Theory-Context-Characteristics-Methodology framework. Through this approach, (1) SLR provides a detailed synthesis of green skepticism research to date, (2) Lexicometric analysis aids in the identification of key themes investigated in green skepticism research to date, and (3) the TCCM framework assists in identifying crucial avenues for future research endeavors in the realm of green skepticism.

Authors: Pam Pedram , Behrooz Maryam , Jamali Mehrdad , Ghorbani Hosna , Hiradfar Amirataollah , Rezamand Azim , Ghoreishi Zohreh
Published: October 2024

Purpose

The purpose of this study is to investigate the relationship between dietary total antioxidant capacity (DTAC) and the dietary inflammatory index (DII) with inflammatory status in children recently diagnosed with Acute Lymphoblastic Leukemia (ALL). As the relationship between diet quality scores and inflammation remains uncertain in this population, the authors carried out a hospital-based cross-sectional study.

Design/methodology/approach

The study used a cross-sectional design involving 54 children recently diagnosed with ALL. Dietary data was collected using a 147-item semi-quantitative food frequency questionnaire developed for the Tehran Lipid and Glucose Study. Inflammatory status was evaluated using various indicators like C-reactive protein (CRP), neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio (PLR), monocyte-to-lymphocyte ratio (MLR), Glasgow prognostic score (GPS) and Complete blood count-based inflammatory score.

Findings

The authors found no significant relationship between DII with inflammatory indices and length of hospitalization in patients. However, a significant inverse relationship was observed between the antioxidant indices ferric-reducing ability of plasma, total reactive antioxidant potential and Trolox equivalent antioxidant capacity with the inflammatory index MLR, respectively (ß: −0.19, p = 0.001), (ß: −0.42, p = 0.02), (ß: −0.53, p = 0.005). Also, a significant inverse relationship between FRAP and CRP was observed in the crude model (ß: −0.13, p = 0.05). FRAP was also inversely correlated with GPS and PLR, respectively (ß: −0.08, p = 0.02), (ß: −0.26, p = 0.03). No additional significant links were discovered between food scores and the outcomes studied.

Originality/value

This study found no link between DII with inflammatory markers or hospitalization duration in children with ALL. However, the authors did observe a noteworthy inverse relationship between DTAC and certain inflammatory markers like MLR. To achieve more dependable findings, further research in this area is necessary.

Thus, future researchers will find underlying literature on IT capabilities in the context of business a rich and varied literature involving these major themes.
Time‐lapse inversion of self‐potential data through particle filtering
Authors: Cui Yi‐An , Peng Yuankang , Xie Jing
Published: October 2024

In environmental sciences, comprehending the movement of subsurface contaminants is crucial for formulating effective remediation measures. The self‐potential (SP) method has become a common tool for delineating landfill contamination plumes. Contaminant diffusion or migration represents dynamic processes, with corresponding SP responses evolving over time. However, conventional SP interpretation approaches have predominantly relied on static single‐frame inversion, overlooking the temporal correlation in time‐series SP data and resulting in cumulative errors. To tackle this challenge, we introduce a novel method for time‐lapse inversion of SP data leveraging particle filtering. This approach recursively refines the priori state model through posteriori observations to achieve precise estimations of dynamic models. Specifically, a spherical polarization model is deployed to establish the state equations of underground contaminant diffusion and transport models, whereas the observation model is derived through forward modeling. The proposed method is validated using two synthetic examples and one lab‐measured dataset. The findings demonstrate the efficacy of the time‐lapse inversion algorithm in precisely estimating dynamic models, outperforming static single‐frame inversion based on the particle swarm optimization algorithm. The posteriori distribution of particles approximates a bell‐shaped distribution, with the true state closely positioned near the peak probability. Therefore, we affirm that conducting time‐lapse inversion of time‐series SP data through particle filtering is an effective and dependable approach for accurately estimating dynamic model states.
Mapping pathogenic fungi in decayed Norway spruce stands: Insights from harvester positional data
Authors: Lara Wilson , Astrup Rasmus , Hietala Ari M. , Maleki Kobra , Belbo Helmer , Antón‐Fernández Clara
Published: October 2024

Root and butt rot caused by pathogenic fungi in the genera Heterobasidion and Armillaria is a pressing issue in managed Norway spruce forests. The disease results in financial losses for the forest owners and reduces the volume of wood that can be used in long‐lived products. Pathogenic wood decay fungi spread either with the aid of airborne spores or via mycelial growth among neighbouring trees, the latter leading to clustering (tendency of decayed trees to be in close proximity relative to their neighbouring trees) of decay‐affected trees in forests. Understanding the spatial patterns of the decay‐affected trees at the forest stand level is vital for designing management strategies to address this problem.

We examined decay clustering in 273 clear‐cut Norway spruce stands in Norway using harvester‐recorded data on spatial occurrence of decayed and healthy Norway spruce trees. We tested clustering using three global‐cluster tests that account for population density and distribution, evaluating clustering without identifying specific cluster locations.

The proportions of clustered and non‐clustered stands differed depending on the statistical test used for clustering assessment, resulting in overall agreement of 32.8% for clustered and 36.9% for non‐clustered. Clustered stands exhibited a median cluster distance (maximum distance between the decay‐affected trees within a cluster) of 12 m (Inter‐Quantile Range, IQR, 6–20 m) and a median of 6 (IQR 3–16) nearest neighbour trees (number of decayed trees forming a cluster), estimates comparable with prior studies focused on assessment of trees infected by mycelial spread of the same fungal individual. The decay incidence in the clustered stands was 16.24%, while the non‐clustered stands had a butt‐rot incidence of 20.97%. In clustered stands the average number of trees per hectare was higher (693) than in non‐clustered stands (553).

Synthesis and applications: Our study demonstrates that Norway spruce stands display a diverse range of spatial patterns of butt rotted trees. We found that higher densities of Norway spruce trees probably facilitate the vegetative spread of pathogenic wood decay fungi, leading to clustering of decay‐affected trees. To disrupt the spread of decay fungi between tree generations, precision planting of trees other than Norway spruce around infested stumps of prior generation trees has been recommended by earlier studies. We discussed the potential of using harvester‐derived geoposition data for butt‐rotted trees upon planning and execution of forest regeneration.

Forecasting the effects of global change drivers on ecosystems is one of the most pressing challenges for scientists worldwide. Particularly, climate change and exotic pathogens might have a large impact on plant community dynamics and ecosystem functioning through changes in carbon uptake and sinks. Nevertheless, we still have a poor understanding of the combined effects of these two drivers on plant communities.

Here, we explored the impact of rainfall reduction and exotic pathogens on the carbon balance of Mediterranean tree species. For this, we performed a 3‐year field experiment taking advantage of rainfall exclusion infrastructures (30% exclusion) installed in the southernmost European oak forests invaded by the aggressive exotic pathogen Phytophthora cinnamomi. We measured a set of 10 variables representative of tree carbon sources (photosynthetic rates) and sinks (primary production, reproduction, defence, and reserves) in adult trees of three species in two forest types: closed forests of Quercus suber and Q. canariensis, and open woodlands of Q. suber and Olea europaea.

We found a large variability in the sensitivity of the different carbon sources and sinks to the effects of drought and pathogens, from variables highly sensitive to both factors (carbon fixation and reproduction, root chemistry) to variables only responsive to drought (litter production) or totally unresponsive (tree trunk, leaf chemistry). Although negative effects predominated, positive effects of rainfall exclusion were also detected in wet years, likely due to a reduction of pathogen abundance in drier soil. Trade‐offs between carbon sinks appeared in all tree species, but rainfall exclusion only modified trade‐offs in Q. suber, the species most susceptible to P. cinnamomi.

Synthesis. We provide evidence on the complexity of the combined effects of abiotic (drought) and biotic (pathogens) global change drivers on carbon source and sinks of adult trees, including both negative direct effects and positive indirect effects. Our results showed that these effects varied among co‐existing species, particularly for carbon sinks directly related to tree demography (reproduction). Therefore, long‐term changes in the structure of Mediterranean mixed forests might be expected towards the dominance of species highly resistant to both drought and pathogens.
Value‐added utilization technologies for seaweed processing waste in a circular economy: Developing a sustainable modern seaweed industry

The global seaweed industry annually consumes approximately 600,000 tons of dried algal biomass to produce algal hydrocolloids, yet only 15–30% of this biomass is utilized, with the remaining 70–85% discarded or released as scum or wastewater during the hydrocolloid extraction process. This residual biomass is often treated as waste and not considered for further commercial use, which contradicts the principles of sustainable development. In reality, the residual algal biomass could be employed to extract additional biochemical components, such as pigments, proteins, and cellulose, and these ingredients have important application prospects in the food sector. According to the biorefinery concept, recycling various products alongside the principal product enhances overall biomass utilization. Transitioning from traditional single‐product processes to multi‐product biorefineries, however, raises operating costs, presenting a significant challenge. Alternatively, developing value‐added utilization technologies that target seaweed waste without altering existing processes is gaining traction among industry practitioners. Current advancements include methods such as separation and extraction of residual biomass, anaerobic digestion, thermochemical conversion, enzymatic treatment, functionalized modification of algal scum, and efficient utilization through metabolic engineering. These technologies hold promise for converting seaweed waste into alternative proteins, dietary supplements, and bioplastics for food packaging. Combining multiple technologies may offer the most effective strategy for future seaweed waste treatment. Nonetheless, most research on value‐added waste utilization remains at the laboratory scale, necessitating further investigation at pilot and commercial scales.

Fermented fruits and vegetables (FFVs) are not only rich in essential nutrients but also contain distinctive flavors, prebiotics, and metabolites. Although omics techniques have gained widespread recognition as an analytical strategy for FFVs, its application still encounters several challenges due to the intricacies of biological systems. This review systematically summarizes the advances, obstacles and prospects of genomics, transcriptomics, proteomics, metabolomics, and multi‐omics strategies in FFVs. It is evident that beyond traditional applications, such as the exploration of microbial diversity, protein expression, and metabolic pathways, omics techniques exhibit innovative potential in deciphering stress response mechanisms and uncovering spoilage microorganisms. The adoption of multi‐omics strategies is paramount to acquire a multidimensional network fusion, thereby mitigating the limitations of single omics strategies. Although substantial progress has been made, this review underscores the necessity for a comprehensive repository of omics data and the establishment of universal databases to ensure precision in predictions. Furthermore, multidisciplinary integration with other physical or biochemical approaches is imperative, as it enriches our comprehension of this intricate process.
