Published: January 2025

Abstract
In the contemporary landscape of digital transformation (DT), the wave of artificial intelligence (AI) is radically restructuring the managerial processes of organizations. As a result, the influence of top managers is emerging as a determining factor in the effectiveness of business strategies related to AI innovation. Academics have provided a large body of literature on this topic, drawing on upper echelons theory, which states that top managers' leadership influences companies' strategic decisions and performance. Leaders have revolutionized their roles and skills to exploit the full potential of AI and integrate it into the business decision-making process effectively. However, given the fragmented nature of existing studies, a systematic literature review is needed to consolidate and clarify how AI impacts top managers' leadership. This paper presents findings involving bibliometric and content analysis tools, examining 63 articles from 31 highly ranked academic journals. Three research clusters emerge: (1) AI-driven skills of top managers' leadership; (2) factors driving top managers' decision to adopt AI in organizations; and (3) the strategic use of AI. The article contributes to upper echelons theory, providing a holistic perspective on top managers' leadership in the AI era and a guidance framework for successfully integrating AI in businesses. Finally, the study offers scholars avenues for future research and provides practical insights for top managers seeking to harness AI technologies to enhance their strategic leadership in organizations.

Published: January 2025

Abstract
Working over an arbitrary field of characteristic different from 2, we extend the Skjelbred-Sund method to compatible Lie algebras and give a full classification of nilpotent compatible Lie algebras up to dimension 4. In case the base field is cubically closed, we find that there are three isomorphism classes and a one-parameter family in dimension 3, and 12 isomorphism classes, 6 one-parameter families and one 2-parameter family in dimension 4.

Published: January 2025

Abstract
In the era of environmental degradation and resource scarcity, the concept of circular economy (CE) has emerged as a pivotal strategy to transform the contemporary industrial landscape. As an integral component of the 10R framework, remanufacturing is emerging as a production strategy that revitalizes end-of-life (EOL) products to a like-new condition, fostering a more sustainable production and consumption. Despite its immense environmental and economic benefits, the implementation of remanufacturing practices is confronted with a multitude of challenges, including sourcing of EOL products, managing component variability, and arbitrary failure rates that result in major process inefficiencies. This paper embarks on the definition of functional and non-functional requirements for remanufacturing production planning and control (RPPC) to establish a systematic approach to address the existing challenges and uncertainties that arise in remanufacturing systems. Based on the synthesis of a comprehensive literature study, eight functional requirements and a total of 48 associated key performance measures are derived and contextualized in a coherent conceptual framework. This establishes a consensus to mitigate the impacts caused by uncertainty in remanufacturing. The feasibility of the conceptual framework is validated in an industrial case study with an OEM remanufacturer of electric power steering products. The findings of this research paper advance the field of RPPC and offer guidance to industrial decision-makers to evaluate and optimize their remanufacturing production systems.
New developments and guideline updates for HFMI treatment for improving the fatigue strength of welded joints
Authors: Marquis G. B. , Barsoum Z. , Leitner M. 
Published: January 2025

Abstract

High-frequency mechanical impact (HFMI) has established itself as a reliable, effective, and user-friendly method for a post-weld fatigue strength improvement technique for welded structures. HFMI can be implemented as an important element of lightweight design for new structures and as a tool for the rehabilitation of structures in service. The first IIW recommendations for HFMI treatment were developed over several years and published in 2016. An abundance of new research and test data confirms the important elements of that guideline. However, it also demonstrated that certain portions of those recommendations need to be clarified, expanded, and improved. These include:

The scope of the guidelines for steels with yield strengths from 960 to 1300 MPa

Relaxing the fatigue geometry requirement of the weld profile prior to HFMI treatment and the groove dimension following treatment

Presenting fatigue strength modification factors also numerically as an alternative to modifying the fatigue class

Incorporating the updated thickness correction factors from the newest IIW Fatigue Design Recommendations

Adding a series of tables that summarize the rules for defining the appropriate fatigue strength for different combinations of material strength, load ratio, stress range, and assessment method

Provide guidelines on HFMI treatment of prefatigued structures

Present a methodology for verifying the effectiveness of HFMI devices based on documentation and experimental data

This paper presents details of this new information that is being incorporated into a revised IIW recommendations for HFMI treatment for improving the fatigue strength of welded joints.
Optimizing two-photon polymerization for rapid and high-resolution prototyping of low-friction microtextured surfaces
Authors: Bornillo Kristal , Sorgato Marco , Lucchetta Giovanni 
Published: January 2025

Abstract
Low-friction surfaces enhance performance across various sectors, such as boosting fuel efficiency in transportation and augmenting precision, safety, and comfort in medical devices. Given these benefits, there is a pressing need to investigate how the geometric characteristics of microtextured surfaces can effectively reduce friction, a process that demands precise geometric control. This study explores the application of Two-Photon Polymerization (TPP) as a high-resolution additive manufacturing technique for prototyping microtextured surfaces used in friction studies. TPP’s ability to create precise microstructures makes it an ideal tool for understanding the impact of geometrical factors on friction. However, a significant trade-off exists between print time and quality, particularly for large samples. The TPP parameters, including laser power, scan speed, hatch, and slice distances, were fine-tuned to cater to friction application and achieve a balance between resolution and efficiency. A hybrid fill mode combining solid, shell and scaffold printing was developed to reduce print time while maintaining surface integrity. Friction tests demonstrated that the TPP-printed microdimpled samples effectively reduced friction, highlighting the potential of TPP as a prototyping tool for tribological applications.
Sounds of Silence: Using the Stereotype Content Model to Understand Perceptions of Introverts and Extraverts at Work
Authors: McCord Mallory A. 
Published: January 2025

Abstract
This paper drew on the stereotype content model (SCM) to clarify cultural stereotypes about introverted and extraverted people at work to increase our understanding of the stereotype-driven process that may lead to negative responses to introversion and subsequent detriment to employee health and well-being. The hypothesis that introverted workers would be rated as lower in warmth and competence than extraverted workers was examined across three studies. Study 1 used qualitative content analyses to assess open responses that freely described introverted and extraverted colleagues. Study 2 tested the hypothesis quantitatively using established measures of warmth and competence. Finally, Study 3 tested if one’s self-identified personality impacted perceptions of warmth and competence. Across all studies, introverted employees were endorsed as being lower in warmth and competence than extraverted employees. In Study 3, warmth and competence stereotypes held regardless of one’s identification as introverted or extraverted. Finally, social interaction requirements of the job moderated perceptions of competence in Study 1, but not in Study 2 or 3. The present findings extend the SCM to new groups and provide empirical evidence to support a key driver in negative responses to introversion in the workplace. The results also suggest that job demands and personality identity salience are important considerations, and a need for organizations to engage in best practices to reduce the negative impact of these stereotypes on employees’ health and well-being.
Scott of the Antarctic, the missing relic

Published: January 2025

Abstract
The deaths in the Antarctic of Captains Robert Falcon Scott and Lawrence “Titus” Oates are the most examined in almost all exploration. However, one object, until today unknown, gives a clue to the real story of the last three days of the Terra Nova expedition leaders. This is the sextant that Captain Scott had with him throughout his career until his death, passed from Kathleen Scott to Peter Scott and thence to its current owner. The sextant, its history and the meaning of the relic are set out before the public for the first time.

Abstract
The information deployment on social networks through word-of-mouth spreading by online users has contributed well to forming opinions, social groups, and connections. This process of information deployment is known as information diffusion. Its process and models play a significant role in social network analysis. Seeing this importance, the present paper focuses on the process, model, deployment, and applications of information diffusion analysis. First, this article discusses the background of the diffusion process, such as process, components, and models. Next, information deployment in social networks and their application have been discussed. A comparative analysis of literature corresponding to applications like influence maximization, link prediction, and community detection is presented. A brief description of performative evaluation metrics is illustrated. Current research challenges and the future direction of information diffusion analysis regarding social network applications have been discussed. In addition, some open problems of information diffusion for social network analysis are also presented.
Amplified Bimodal Distribution of Western North Pacific Tropical Cyclone Lifetime Maximum Intensity

Published: January 2025

AbstractThe impact of a warming climate on tropical cyclones (TCs) remains unclear. Here, we find that the probability density function for western North Pacific TC lifetime maximum intensity (LMI) has an amplified bimodal distribution in recent years. This change implies a trend toward more extreme TCs and fewer moderate TCs. Changes in the TC LMI distribution are associated with alterations in the occurrence of rapidly intensifying TCs. Changes in TC tracks, due to alterations in the steering flow linked to a weakening Hadley cell, cause more TCs to move northwestward into a more favorable environment for intensification with large ocean heat content. Consequently, more rapidly intensifying TCs reach higher intensities, significantly contributing to the observed amplified bimodal distribution. These findings provide new insights into changes in TC intensity and highlight the increasing threat to coastal areas from more intense TCs in a warming climate.

Abstract
Nanoelectromechanical systems (NEMS) based on atomically-thin tungsten diselenide (WSe2), benefiting from the excellent material properties and the mechanical degree of freedom, offer an ideal platform for studying and exploiting dynamic strain engineering and cross-scale vibration coupling in two-dimensional (2D) crystals. However, such opportunity has remained largely unexplored for WSe2 NEMS, impeding exploration of exquisite physical processes and realization of novel device functions. Here, we demonstrate dynamic coupling between atomic lattice vibration and nanomechanical resonances in few-layer WSe2 NEMS. Using a custom-built setup capable of simultaneously detecting Raman and motional signals, we accomplish cross-scale mode coupling between the THz crystal phonon and MHz structural vibration, achieving GHz frequency tuning in the atomic lattice modes with a dynamic gauge factor of 61.9, the best among all 2D crystals reported to date. Our findings show that such 2D NEMS offer great promises for exploring cross-scale physics in atomically-thin semiconductors.

Abstract
The spatial role of M1 and M2 tumor-associated macrophages (M1/M2 TAMs) in precision medicine remains unclear. EGFR and TP53 are among the most frequently mutated genes in lung adenocarcinoma. We characterized the mutation status and density of M1/M2 TAMs within tumor islets and stroma in 117 lung adenocarcinomas using next-generation sequencing and immunohistochemistry, respectively. Stromal M1 TAMs were positively correlated with disease progression and smoking history. In contrast, islet M1/M2 TAMs were predominantly found in tumors with wild-type TP53 (wtp53) but not associated with EGFR status. The presence of wtp53 was associated with the spatial distribution of M1/M2 TAMs in tumor islets and stroma. Additionally, dominance of islet M1 TAMs and M1-signature were significantly associated with improved survival in patients with wtp53 lung adenocarcinoma, unlike in those with mutant TP53. Conditioned medium from M1 macrophages (M1 CM) induced apoptosis in wtp53 cells through increased p53 accumulation. We found that interferons in M1 CM activate JAK1/TYK2 via IFNARs, leading to enhanced STAT1 expression and Y701 phosphorylation. This activation facilitates p53-STAT1 interactions, reduces the interaction between p53 and MDM2, and subsequently decreases p53 ubiquitination. M1 CM inhibited tumorigenesis, and silencing p53 reduced the anti-tumor efficacy of polyinosinic:polycytidylic acid (poly I:C) in vivo. Furthermore, higher M1-signature was significantly associated with better responses and survival following anti-PD1 treatment in wtp53 melanomas. IFNs/STAT1/p53 signaling was critical for the anti-tumor activity of M1 macrophages. These findings suggest that p53 modulates the spatial balance of M1/M2 TAMs, and the tumoricidal effects of M1 TAMs depend on p53 status. Thus, p53 companion diagnostics could facilitate the development of M1-oriented therapies, which may be particularly beneficial for wtp53 patients when combined with immunotherapy.

Abstract
One of the key advantages of perovskite light-emitting diodes (PeLEDs) is their potential to achieve high performance at much higher current densities compared to conventional solution-processed emitters. However, state-of-the-art PeLEDs have not yet reached this potential, often suffering from severe current-efficiency roll-off under intensive electrical excitations. Here, we demonstrate bright PeLEDs, with a peak radiance of 2409 W sr−1 m−2 and negligible current-efficiency roll-off, maintaining high external quantum efficiency over 20% even at current densities as high as 2270 mA cm−2. This significant improvement is achieved through the incorporation of electron-withdrawing trifluoroacetate anions into three-dimensional perovskite emitters, resulting in retarded Auger recombination due to a decoupled electron-hole wavefunction. Trifluoroacetate anions can additionally alter the crystallization dynamics and inhibit halide migration, facilitating charge injection balance and improving the tolerance of perovskites under high voltages. Our findings shed light on a promising future for perovskite emitters in high-power light-emitting applications, including laser diodes.

Published: January 2025

Abstract
The enantioselective domino Heck/cross-coupling has emerged as a powerful tool in modern chemical synthesis for decades. Despite significant progress in relative rigid skeleton substrates, the implementation of asymmetric Heck/cross-coupling cascades of highly flexible haloalkene substrates remains a challenging and and long-standing goal. Here we report an efficient asymmetric domino Heck/Tsuji−Trost reaction of highly flexible vinylic halides with 1,3-dienes enabled by palladium catalysis. Specifically, the Heck insertion as stereodetermining step to form ƞ3 allyl palladium complex and in situ trapping with nucleophiles enable efficient Heck/etherification in a formal (4 + 2) cycloaddition manner. Engineering the Sadphos bearing androgynous non-C2-symmetric chiral sulfinamide phosphine ligands are vital component in achieving excellent catalytic reactivity and enantioselectivity. This strategy offers a general, modular and divergent platform for rapidly upgrading feedstock flexible vinylic halides and dienes to various value-added molecules and is expected to inspire the development of other challenging enantioselective domino Heck/cross-couplings.

Abstract
Gammaherpesviruses are DNA tumor viruses that establish lifelong latent infections in lymphocytes. For viruses such as Epstein-Barr virus and murine gammaherpesvirus 68, this is accomplished through a viral gene-expression program that promotes cellular proliferation and differentiation, especially of germinal center B cells. Intrinsic host mechanisms that control virus-driven cellular expansion are incompletely defined. Using a small-animal model of gammaherpesvirus pathogenesis, we demonstrate in vivo that the tumor suppressor p53 is activated specifically in B cells latently infected by murine gammaherpesvirus 68. In the absence of p53, the early expansion of murine gammaherpesvirus 68 latency greatly increases, especially in germinal center B cells, a cell type whose proliferation is conversely restricted by p53. We identify the B cell-specific latency gene M2, a viral promoter of germinal center B cell differentiation, as a viral protein sufficient to elicit a p53-dependent anti-proliferative response caused by Src-family kinase activation. We further demonstrate that Epstein-Barr virus-encoded latent membrane protein 1 similarly triggers a p53 response in primary B cells. Our data highlight a model in which gammaherpesvirus latency gene-expression programs that promote B cell proliferation and differentiation to facilitate viral colonization of the host trigger aberrant cellular proliferation that is controlled by p53.

Abstract
Acute liver failure is a rapidly progressing, life-threatening condition most commonly caused by an overdose of acetaminophen (paracetamol). The antidote, N-acetylcysteine (NAC), has limited efficacy when liver injury is established. If acute liver damage is severe, liver failure can rapidly develop with associated high mortality rates. We have previously demonstrated that alternatively, activated macrophages are a potential therapeutic option to reverse acute liver injury in pre-clinical models. In this paper, we present data using cryopreserved human alternatively activated macrophages (hAAMs)—which represent a potential, rapidly available treatment suitable for use in the acute setting. In a mouse model of APAP-induced injury, peripherally injected cryopreserved hAAMs reduced liver necrosis, modulated inflammatory responses, and enhanced liver regeneration. hAAMs were effective even when administered after the therapeutic window for NAC. This cell therapy approach represents a potential treatment for APAP overdose when NAC is ineffective because liver injury is established.

Abstract
The early evolution of dust in protoplanetary disks is dominated by sticking collisions. However, this initial phase of particle growth faces constraints, notably from destructive encounters. To find the maximum particle size achievable, we studied collisional processes during a prolonged microgravity experiment aboard a suborbital flight. Specifically, we describe an impact erosion limit. We observed individual basalt beads, each measuring 0.5 mm in diameter, colliding with and either eroding or adhering to a cluster several centimetres in size. This cluster, formed from tribocharged particles, simulates an electrostatic growth phase that surpasses the classical bouncing barrier. We found a threshold velocity of about 0.5 m s−1, which separates additive and erosive impacts of individual beads. Numerical simulations of grains impacting clusters, for both low and high charge constituents, corroborate the experimental findings of surface erosion within the observed velocity range. This specific velocity threshold supports the potential formation of pebbles several centimetres in size within protoplanetary disks. Such dimensions place these pebbles well into a regime in which hydrodynamic interactions might facilitate the formation of planetesimals.
