Repeated environmental change mitigates inter-individual inequal food gain in a group foraging experiment of crow
Authors: Niki Yasuyuki , Takano Mayu , Izawa Ei-Ichi 
Published: February 2025

AbstractAnimal group foraging produces unequal distributions of food gains among participants because of individual differences, such as dominance rank. However, external environmental factors, such as fluctuation of food spatial distribution over time, may mitigate the impact of social features on food acquisition. Earlier experimental studies focused on a group’s internal environment or were conducted in stable and unchanging environments. Here, we investigated how environmental fluctuations affect food acquisition at group and individual levels in captive large-billed crows (Corvus macrorhynchos) by changing the relationship between feeding sites and food quantity. We found that foraging efficiency and food distribution equality initially declined after environmental changes, gradually increased, and improved with repeated long-term environmental fluctuations. The influence of sex was found, while that of dominance rank was not. The present results provide the first experimental evidence to suggests that environmental fluctuations mitigate inequal food gain among individuals in group foraging.

Successful axonal regeneration is driven by evolutionarily conserved metabolic reprogramming
Authors: Zhang Anyi , Bergmans Steven , Van Dyck Annelies , Beckers An , Moons Lieve , Masin Luca 
Published: February 2025

SummaryUnlike mammals, zebrafish can regrow axons after injury and restore circuit function in the central nervous system (CNS). Mitochondria have been identified as key players in this process, but how different metabolic pathways work together to sustain regeneration remains unclear. Using RNA sequencing of adult zebrafish retinal ganglion cells after optic nerve crush injury, we found that oxidative phosphorylation is downregulated during axonal regrowth. Simultaneously, the thioredoxin antioxidant system was upregulated, likely to limit oxidative damage. Additionally, we observed an integrated upregulation of glycolysis and the pentose phosphate pathway during the initial regrowth phases, possibly to provide energy and supplying NADPH for biosynthesis and antioxidant responses. We show that this metabolic reprogramming is evolutionarily conserved, as a comparable one occurs in the pro-regenerative mammalianPtenandSocs3co-deletion model. Inhibiting glycolysis and thioredoxin in zebrafish impairs axonal regrowth, suggesting that targeting these pathways could enhance CNS regeneration in mammals.

Published: February 2025

AbstractOdor cues in nature are sparse and highly fluctuating due to turbulent transport. To investigate how animals perceive these intermittent cues, we developed a behavioral task in which head-restrained mice made binary decisions based on the total number of discrete odor pulses presented stochastically over several seconds. Mice readily learned this task, and their performance was well-described by widely used decision models. Logistic regression of binary choices against the timing of odor pulses within the respiratory cycle revealed that mice placed higher perceptual weight to stimuli arriving during inhalation than exhalation, a phase dependency that strongly correlated with the magnitude of responses in olfactory sensory neurons. The population response of anterior piriform cortex (APCx) neurons to odor pulses was also modulated by respiration phase, although individual neurons displayed varying levels of phase-dependence. Single APCx neurons responded stochastically and transiently to odor pulses, leading to a representation that carries signatures of sensory evidence, but not its accumulation. Our study reveals that mice can integrate intermittent odor signals across dozens of breaths, but respiratory modulation of sensory inputs imposes limits on information acquisition that cortical circuits cannot overcome to improve behavior.

AbstractBackground:Advanced solid cancers present significant treatment challenges due to their genomic heterogeneity and resistance. Liquid biopsies, specifically circulating tumour DNA (ctDNA), have emerged as promising tools to support treatment decision making. However, evidence regarding their implementation in routine care remains limited.Methods:LIQPLAT is a single-arm trial (SAT), assessing the feasibility of implementing ctDNA measurements in the usual care of patients with advanced solid cancers excepting primary brain tumours, at the University Hospital Basel. Patients are randomly invited from an ongoing research registry to take part in the SAT. We aim to include 150 randomly invited patients to receive ctDNA measurements alongside standard care. CtDNA samples are collected at baseline, between the second and third months, fifth and seventh months after cancer treatment start, and during serious clinical events such as disease progression or treatment changes. Results are evaluated by a molecular tumor board to guide clinical management. Feasibility outcomes include detectability of ctDNA, identification of actionable alterations, and analysis turnaround time. Other outcomes include patient-reported quality of life, progression-free survival and overall survival, time to next treatment line, and unscheduled hospital and emergency visits, all obtained from routine healthcare data.Discussion:LIQPLAT will examine the implementation of ctDNA measurements in routine care. The random selection for invitation to this SAT within an existing registry embedded in routine care creates a representative sample and allows for better assessment of implementation and generalization of findings.Trial registration:The trial is registered atclinicaltrials.gov(2024-04-11,NCT06367751) and kofam.ch (2024-03-15, SNCTP000005844).
Common Neural Choice Signals reflect Accumulated Evidence, not Confidence

Published: February 2025

AbstractWhile much research has investigated decision confidence, its neural underpinnings remain unclear. Although several studies have shown that centro-parietal EEG signals correlate with the reported level of confidence, according to recent computational work these signals reflect evidence which feeds into the computation of confidence, but they do not themselves track confidence. To test this prediction, we capitalized on our recent finding that a causal manipulation of prior beliefs selectively affects confidence, while leaving objective task performance unaffected. Using EEG recordings, we tested whether neural signals known to correlate with confidence (CPP and Pe) reflect evidence accumulation or confidence. Behaviorally, we replicated the finding that manipulating prior beliefs causally and selectively affected confidence without changing objective task performance. The EEG data showed a monotonic relation between the reported level of confidence and both CPP and Pe amplitudes. Importantly, this finding is compatible both with the theory that these signals track confidence as well as with the alternative theory that they track accumulated evidence. Critically, both neural signals were insensitive to the influence of prior beliefs on confidence, showing that they reflect the accumulated evidence that is used by the system to compute confidence, instead of directly reflecting confidence. Likewise, oscillatory activity in alpha and beta band was insensitive to the influence of prior beliefs on confidence. Decoding analyses revealed that the brain does hold shared representations for prior beliefs and confidence, and we identified a frontal signal that is sensitive to both confidence and prior beliefs. These findings are in line with recent views suggesting that the CPP and the Pe reflect evidence accumulation, which is combined with prior beliefs to form a confidence judgment.
Breakup of positronium by Compton scattering of high-energy photons
Authors: Najjari B. , Pedain C. , Müller C. , Voitkiv A. B. 
Published: February 2025

We study the breakup of positronium (Ps) by Compton scattering in the range of photon energies, where the motion of the electron and the positron remains nonrelativistic and the process is dominated by the interaction terms ∼Â2, where Â is the vector potential of the photon field. In this study we first compare the total cross section for this process with the total cross section for the positronium breakup by photoabsorption, showing that they become equal at the incident photon energy ℏωiPs≈2.2 keV and that—due to strong (and opposite) dependencies of these cross sections on the photon energy—the Compton scattering rapidly becomes by far the dominant breakup channel when the photon energy exceeds ℏωiPs. Then we explore the energy and angular spectra of electrons and positrons, which are emitted from the positronium in collisions with high-energy photons, and of the scattered photons. By analyzing the physical mechanisms, which determine the properties of the spectra, we demonstrate that in such collisions the atomic particles can be clearly subdivided into the “participator,” on which the incident photon scatters, and the “spectator,” which is not directly involved in the scattering process. The results for the positronium breakup are compared with the corresponding results for the ionization of atomic hydrogen and the similarities in these processes as well as the differences between them are discussed.

Socially responsible cocreation in service recovery: the role of pride in prosocial compensation
Authors: Alhouti Sarah (Sa’arah) , Lindsey Hall Kristina K. , Kuo Andrew , Baker Thomas L. 
Published: February 2025

Purpose
This study explores the incorporation of prosocial compensation in service recoveries by allowing customers to cocreate the process through compensation choice, explains the underlying mechanism driving these results and identifies a boundary condition for these effects.

Design/methodology/approach
Three scenario-based experimental studies are conducted to test the proposed hypotheses.

Findings
Incorporating cocreation in a service recovery featuring prosocial compensation can outperform purely financial compensation (i.e. monetary-only) if the customer is given a choice. Moreover, pride is higher for customers who choose prosocial compensation (i.e. donations) as part of a service recovery. These findings are contingent on the firm’s reputation, namely, its corporate social responsibility (CSR) authenticity, such that companies with high (vs low) CSR authenticity perceptions benefit more in terms of enhanced pride given cocreated prosocial recoveries.

Research limitations/implications
Drawing on service-dominant logic and social exchange theory, the findings of this research suggest that incorporating prosocial compensation, an element of CSR, as part of a cocreated service recovery strategy can enhance pride and repurchase intent.

Practical implications
This research demonstrates instances where prosocial compensation can outperform monetary-only compensation, leading to higher repurchase intent, highlighting conditions for this to occur and offering prescriptions for managers to implement these strategies in service recoveries.

Social implications
Cocreating service recoveries with prosocial compensation, like donations, boosts customer pride and strengthens relationships. Firms with authentic CSR perceptions benefit most, addressing customers’ emotional and economic needs while enhancing community goodwill.

Originality/value
This work uniquely explores the effect of cocreated recoveries using prosocial compensation on pride and repurchase intent.
Invisible to influential: customer emotional labour’s impact on luxury services
Authors: Park Jungkun , Chen Yuhsuan 
Published: February 2025

PurposeThis study aims to empirically test the influence of customer perceptions of employee emotional labour (CPEL) and customer emotional labour (CEL) on perceived service quality, satisfaction with service and repurchase intentions in luxury retail. It further examines the moderating role of perceived customer interactivity in the relationships among CPEL, CEL and service outcomes.Design/methodology/approachAn online survey of 249 customers with experience in offline luxury service interactions was conducted. Statistical analyses and hypothesis testing were performed using SPSS and AMOS.FindingsThis study highlights the critical role of customer perceptions of employee deep acting and customer surface acting in shaping perceived service quality. It demonstrates that customers’ efforts to regulate their emotions, similar to employees’ efforts, significantly affect service outcomes. Additionally, the results suggest that perceived customer interactivity significantly moderates only the relationship between CEL and service satisfaction.Originality/valueBy exploring emotional labour from the customers’ perspective within the luxury retail sector, this study offers novel insights into service quality management. It extends the theoretical framework of emotion regulation theory to this context, offering practical implications for enhancing service experiences in developing luxury markets.

Authors: Salustio Janaina , Torres Sando , Azevedo António , Nogueira Silva Fernando Artur , Delgado J.M.P.Q. 
Published: February 2025

PurposePrismatic specimens were fabricated, consisting of two ceramic tiles bonded by an intermediate adhesive mortar layer. To simulate pre-existing defects, an acetate film was strategically inserted into one of the mortar-ceramic interfaces, creating controlled cracks of varying sizes. The specimens were subjected to low-amplitude cyclic loading, inducing simultaneous tensile and shear stresses within the system. The vibrational responses of the samples were recorded, and their frequency-domain amplitudes were analyzed.Design/methodology/approachCeramic tile detachment remains a significant issue in contemporary construction, despite advancements in technology and updates to regulatory standards. The majority of these failures occur at the adhesive mortar-ceramic tile interface due to the combined effects of tensile and shear stresses. While this phenomenon is well-documented, experimental studies assessing the adhesion integrity of façade cladding systems are limited. This study aims to evaluate the adhesion performance of adhesive mortars using a non-destructive vibrational analysis technique.FindingsThe results enabled the characterization of the dynamic behavior of the specimens, identification of frequency regions corresponding to individual components, and formulation of diagnostic criteria for damage detection. Analysis of the resonance spectra also made it possible to identify a peak that can be related to the behavior of the mortar-substrate interface. Additionally, the elastic and dissipated energy metrics were calculated to quantify the system’s mechanical behavior. The study further investigated the impact of crack size, curing time and adhesive mortar type on the overall structural integrity.Originality/valueThis work aims to evaluate the adhesion performance of adhesive mortars using a non-destructive vibrational analysis technique. Resonance frequency measurements have also been used in research to analyze the propagation paths of cracks in metallic samples from aircraft engines. However, despite the widespread use of non-destructive techniques based on resonance frequencies for damage assessment, their application in the field of coating systems seems to be virtually unexplored. Therefore, this research attempts to address this gap by investigating the bond integrity of adhesive mortar joints, focusing on the analysis of the material’s resonance frequencies and their associated peak parameters.

Published: February 2025

PurposeOnline games are highly popular Internet applications. Some games enable players to save game progress and accumulate experiences or changes to avatars during gameplay, whereas some other games do not, requiring players to restart from the beginning each time. That is, games differ in avatar accumulability. However, we do not know whether games should be designed to permit avatar accumulability or not and how it affects players’ gameplay experience and therefore game outcomes, indicating gaps. Research addressing these gaps can inform game makers in designing games that effectively strengthen their players’ game loyalty.Design/methodology/approachWe used social identity theory (SIT) to construct a theoretical model. To test this model, three waves of survey data were gathered from the same 778 participants.FindingsThese findings uniquely indicate that avatar accumulability fosters avatar identification and increases players’ focused immersion, thus increasing players’ loyalty.Practical implicationsGame providers could include game features that enable players to accumulate their avatars’ in-game skins, levels, items (weapons and equipment) and experience points. This accumulability can help strengthen players’ game loyalty.Originality/valueOverall, our study extends SIT by adding a new trigger (avatar accumulability) and two novel consequences of avatar identification (image protection and focused immersion) in avatar-related systems (games or gamified systems). The new trigger offers an actionable means to apply SIT, while the novel consequences verify the value of applying SIT to study online games.

Published: February 2025

Purpose
This research aims to provide a innovative class of shape-memory-responsive cellulosic composites (RCC) for 4D printing, enabling self-activated, reversible shape morphing. By integrating experimental, theoretical, and computational modeling, the study optimizes material behavior, offering precise curvature predictions for advanced biomedical and pharmaceutical applications.

Design/methodology/approach
This study presents an innovative class of shape–memory–responsive cellulosic composites (RCC), with a unique combination of starch and AffnisolTM. RCC-mediated filaments were used to print single-layer strips using fused deposition modeling 3D printing technology. The printed single-layer strip exhibited reversible, contactless and self-activated shape morphing in response to swelling and heat. The programming stage involves the swelling and heating of the composite strip and subsequent shape recovery through heating. The shape deformation during the self-activated programming stage was both estimated and predicted using simple experimental, theoretical and computational tools. The study was conducted at different thicknesses (1.5, 2.0 and 2.5 mm) and temperatures (25°C and 37°C) to validate the performance of the developed model in predicting bending curvature.

Findings
The developed model showed less than a 13.96 % difference in curvature predicted using theoretical and experimental modeling at studied temperatures. At lower thicknesses, the model can predict the bending curvature with less than a 2.0 % difference in curvature. These RCC materials exhibited potential reversible 4D printing capacity and satisfied the adopted approaches and modeling to forecast the bending curvature for reversible 4D printing.

Originality/value
This study introduces a new class of composite materials for potential 4D applications and provides simple predictive models to forecast bending curvature in reversible 4D printing.
