Aperiodicity in mouse CA1 and DG power spectra
Authors: Kühn Gustav , El Rashidy Hussin , Calegari Federico , Dhingra Shonali 
Published: January 2025

ABSTRACTRodent hippocampal power spectra comprise of periodic and aperiodic components. The periodic components (brain rhythms) contain information about the behavioral or cognitive state of the animal. The aperiodic components are rarely studied and their functionality is not well understood, though have shown to be correlated with animal’s age or the excitation-inhibition ratio of the brain region. To study these components in the mouse hippocampus we modified the existing open-source FOOOF toolbox, which was originally optimized for EEG data. First, using simulated data, we show that our modifications decrease the error in assessment of the periodic components from 3% to 0.1%. Second, using tetrode electrophysiological signals, we compare the aperiodic activity within mice hippocampal sub-regions, CA1 and dentate gyrus (DG). Our optimization of FOOOF improved the aperiodic assessment errors by about 50% and were critical in making the first-ever assessments of the aperiodic components in these brain regions. Our results show that the aperiodic parameters in the DG are multi-fold and significantly larger than in CA1, revealing higher excitation and longer timescales in CA1 than DG. Our work highlights the subtle differences in electrophysiology field potentials between hippocampal sub-regions, and presents the improvements needed in the existing open-source toolbox to be able to see such differences.
Eigenvalue based taste breaking of staggered, Karsten-Wilczek, and Boriçi-Creutz fermions with stout smearing in the Schwinger model
Authors: Ammer Maximilian , Dürr Stephan 
Published: January 2025

In two spacetime dimensions staggered fermions are minimally doubled, like Karsten-Wilczek and Boriçi-Creutz fermions. A continuum eigenvalue is thus represented by a pair of near-degenerate eigenvalues, with the splitting δ quantifying the cutoff induced taste symmetry breaking. We use the quenched Schwinger model to determine the low-lying fermionic eigenvalues (with 0, 1 or 3 steps of stout smearing) and analyze them in view of the global topological charge q∈Z of the gauge background. For taste splittings pertinent to would-be zero modes, we find asymptotic Symanzik scaling of the form δwzm∝a2 with link smearing, and δwzm∝a without, for each action. For taste splittings pertinent to nontopological modes, staggered splittings scale as δntm∝ap (where p≃2 with smearing and p=1 without), while Karsten-Wilczek and Boriçi-Creutz fermions scale as δntm∝a (regardless of the smearing level). Large corrections are seen with smearing.

Spectrum of two-flavored spin-zero heavy dibaryons in lattice QCD
Authors: Junnarkar Parikshit M. , Mathur Nilmani 
Published: January 2025

We present the ground state energy spectra of two-flavored heavy dibaryons in the spin-singlet channel. In particular, the ground state masses of ΩllQΩllQ,ΩQlQΩllQ, and ΩQlQΩQlQ states are computed and compared with their respective lowest noninteracting energy levels, where the flavor Q∈(c,b) denotes charm and bottom quarks, and the other flavor l∈s,c,b represents strange, charm and bottom, respectively. Considering their valence quark structures, these hadrons could be thought of as the heavy flavor analogs of spin-singlet nucleon-nucleon states. The gauge configurations employed in this study are highly improved staggered quark ensembles with Nf=2+1+1 flavors, generated by the MILC collaboration, at four lattice spacings, namely a=0.1207, 0.0888, 0.0582, and 0.0448 fm. The aforementioned states are also computed at different quark masses, between ms≤ml≤mb, including at unphysical heavy quark masses, to explore the quark mass dependence of any possible binding. For the dibaryon states ΩbbcΩbbc,ΩccbΩccb, and ΩccbΩbbc, we find a clear evidence of an energy level below their respective noninteracting energy levels. In addition, for these dibaryons at quark masses mc<ml≤mb, a trend is found where the gap, between the lowest energy levels and the respective lowest noninteracting levels, increases as the quark mass ml increases. We also study the heavy quark spin-symmetry and its breaking for these heavy dibaryons.

Phase transition analogs in laser collisions with a dark-field setup
Authors: Gies Holger , Karbstein Felix , Maiwald Lars 
Published: January 2025

Laser pulse collisions are a promising tool for the investigation of light-by-light scattering phenomena induced by quantum vacuum fluctuations. Using the numerical code based on the vacuum emission picture and put forward in [1], we observe a strong dependence of the signal features on the transverse profiles of the colliding laser pulses in the interaction region. For a probe beam tailored such as to feature an annular far-field profile and a pronounced on-axis focus peak counterpropagating a pump beam at zero impact parameter, the signal’s main emission direction can undergo the analog of a phase transition with the beam-waist ratio of the pulses serving as a control parameter. Depending on the pump’s beam profile, this phase transition can be first order (e.g., for a pump with a flat-top far-field profile) or second order (e.g., for a Gaussian pump). From the simulation data, we determine the critical point and extract the corresponding critical exponent for the second-order transition of the main emission direction of the signal in the far field. For this, we improve the performance of the above numerical code, using the phase transition analogs as an example to illustrate the capabilities and limitations of the code and current workflows.

Memory-corrected quantum repeaters with adaptive syndrome identification
Authors: Romanova Alena , van Loock Peter 
Published: January 2025

We address the challenge of incorporating encoded quantum memories into an exact secret key rate analysis for small and intermediate-scale quantum repeaters. To this end, we introduce the check matrix model and quantify the resilience of stabilizer codes of up to eleven qubits against Pauli noise, obtaining analytical expressions for effective logical error probabilities. Generally, we find that the five-qubit and Steane codes either outperform more complex, larger codes in the experimentally relevant parameter regimes or have a lower resource overhead. Subsequently, we apply our results to calculate lower bounds on the asymptotic secret key rate in memory-corrected quantum repeaters when using the five-qubit or Steane codes on the memory qubits. The five-qubit code drastically increases the effective memory coherence time, reducing a phase flip probability of 1% to 0.001% when employing an error syndrome identification adapted to the quantum noise channel. Furthermore, it mitigates the impact of faulty Bell state measurements and imperfect state preparation, lowering the minimally required depolarization parameter for nonzero secret key rates in an eight-segment repeater from 98.4% to 96.4%. As a result, the memory-corrected quantum repeater can often generate secret keys in experimental parameter regimes where the unencoded repeater fails to produce a secret key. In an eight-segment repeater, one can even achieve nonvanishing secret key rates up to distances of 2000 km for memory coherence times of tc=10 s or less using multiplexing. Assuming a zero-distance link-coupling efficiency p0=0.7, a depolarization parameter μ=0.99, tc=10 s, and an 800 km total repeater length, we obtain a secret key rate of 4.85 Hz, beating both the unencoded repeater that provides 1.25 Hz and ideal twin-field quantum key distribution with 0.71 Hz at GHz clock rates.

Published: January 2025

Purpose
The main goal of this study is to develop accounting students’ solidarity with and sensitivity to cooperation for sustainable development. This study also aims to analyze the role of participatory learning activities in developing the dimensions of involvement, critical reflection and thinking analysis.

Design/methodology/approach
This empirical study analyzes a case study activity conducted in accounting seminars with students from different universities in Spain. After completing the activity, the students completed a questionnaire divided into four areas: sociodemographic information, involvement, critical reflection and creativity. Students also answered an open-response question that asked them to propose new activities to enhance their learning experience and contribute more to sustainable development. The study thus used mixed methods, complementing quantitative analysis with qualitative data.

Findings
The multivariate analysis obtained significant results showing that female students were more willing to help and that most students said they were more sensitive to these issues after the participatory learning activity. Furthermore, the items and dimensions analyzed revealed a positive impact of involvement, critical and creative thinking and participatory learning on accounting students’ commitment to cooperation for sustainable development. When students answered the open-response question, they proposed more activities to enhance their learning and improve the functioning of the Non-Governmental Organization’s (NGO’s) beneficiary. HEIs must design more transversal courses aligned with the Sustainable Development Goals in their social science degrees.

Originality/value
The study not only examines university education in sustainable development but goes a step further in trying to involve students in a real development project from a financial and accounting point of view. The study also focuses on education for sustainability, and the project invites the students to think critically, reflect and assess real situations.

Published: January 2025

PurposeDrawing on job demands-resources theory, this paper aims to investigate the impact of workplace spirituality on mindfulness and the subsequent effects of mindfulness on open innovation mindset and job embeddedness. Additionally, it examines the mediating role of mindfulness between workplace spirituality and key outcomes, including open innovation mindset and job embeddedness. Lastly, the study investigates the moderating role of self-efficacy in the relationship between workplace spirituality and mindfulness.Design/methodology/approachThe research utilized multiple sampling techniques to collect data from employees across numerous sectors. A total of 197 viable responses were collected. Partial least squares structural equation modeling (PLS-SEM) was used to test the proposed hypotheses.FindingsThe results indicate that workplace spirituality has a positive impact on mindfulness, which in turn increases employees’ job embeddedness and an open innovation mindset. Additionally, it was found that mindfulness mediates the relationship between workplace spirituality and both job embeddedness and open innovation mindset. Surprisingly and unexpectedly, the results indicate a negative moderating impact of self-efficacy between workplace spirituality and mindfulness.Practical implicationsCultivating a sense of purpose and meaningful work, alongside mindfulness programs and recruitment practices focused on cultural fit, can enhance both employee retention and innovation.Originality/valueLittle to no research exists that clarifies how workplace spirituality impacts employees’ job embeddedness and an open innovation mindset. Notably, the mediating role of mindfulness remains unexplored. This study is among the first to explore the mediating role of mindfulness between workplace spirituality and outcomes such as job embeddedness and an open innovation mindset. Additionally, the moderating role of self-efficacy between workplace spirituality and mindfulness is almost absent in the existing literature. Lastly, the unexpected findings on the role of self-efficacy in this study open fresh avenues for future research.
4D-printed self-forming monofilament structures in material extrusion additive manufacturing
Authors: Zhang Jinnuo , He Ran , Baxevanakis Konstantinos P. , Gleadall Andrew 
Published: January 2025

Purpose
This paper aims to investigate the potential for 4D deformation of the smallest building blocks of the material extrusion additive manufacturing (MEAM) process: single extrudates produced with a single material. In contrast to previous 4D printing approaches where property-variations are realised across multiple layers or with complex composites, this study hypothesises that residual strain varies from top-to-bottom within a single printed extrudate and that this offers an opportunity to achieve controllable 4D printing with the smallest possible resolution (single lines in a single layer).

Design/methodology/approach
The influences of bed temperature, printing temperature, printing speed, extrusion width, extrusion thickness and activation temperature are quantified in terms of residual strain and 4D curvature.

Findings
An almost fourfold variation in curvature was achieved, printing speed and layer thickness greatly affected 4D deformation: the maximum curvature was increased by >600% compared to the minimum curvature when varying printing speed. In addition to rigorous parametric characterisation, a case study demonstrates the 4D deformation of a flat single-layer lattice into a 3D self-formed stent structure comprised of intricate single-extrudate struts. A separate case study demonstrates the resilience of the method by showing results to translate to alternative materials, with alternative printing hardware and with a different 4D activation procedure.

Originality/value
This study successfully proves a new way to achieve intricate 3D structures with the MEAM process, which would be impossible without 4D deformation due to their intricacy and the need for support material. The findings are also relevant to research into undesired warping due to the quantification of residual strain.

Published: January 2025

PurposeThere has been a noticeable increase in review studies exploring the relationship between sport and sustainability; however, these studies significantly overlook the marketing function, creating a critical gap in understanding how sustainable practices can be promoted within the sports industry. The purpose of this study is to build a research agenda of the sport–sustainability domain within the marketing field by using an integrated bibliometric and unsupervised machine learning approach.Design/methodology/approachBibliometric analysis, along with Latent Dirichlet Allocation (LDA) for topic modeling, enabled us to identify key trends and themes in the sport–sustainability domain. The study uses the Scopus and Web of Science (WoS) databases to extract a final dataset of 929 texts (titles, abstracts and keywords) from published research on sport–sustainability domain within the marketing field.FindingsWe decipher the key trends in the literature and segregate them into four broad topics – places, consumers, markets and strategies – to enhance the understanding of this field of inquiry. This study is the first in the sport–sustainability domain to use this integrated approach to review the literature, and the findings lay the groundwork for future research.Originality/valueThis study uses a combined methodology thereby offering distinct advantages over other review approaches.
Metastatic Thymic Mucoepidermoid Carcinoma: The Diagnostic Challenges and Role of CRTC1/MAML2 Translocation in Accurate Diagnosis and Treatment
Authors: Takahashi Toshiaki , Graham Daniel , Wu Evan 
Published: January 2025

ABSTRACTMucoepidermoid carcinoma (MEC) is a subtype of epithelial neoplasms commonly found in salivary glands, but can also be seen in the thymus. Diagnosing MEC of the thymus is sometimes challenging due to its histological similarities with adenosquamous carcinoma (ASC). This case report describes a 64‐year‐old female with a history of metastatic endometrial adenocarcinoma who presented to an oncology clinic with a thymic mass as well as multiple mass lesions in the liver, bone, and abdominal wall. Initially diagnosed as thymic ASC based on histopathology, further genomic profiling revealed a CRTC1/MAML2 translocation, leading to the diagnosis of metastatic MEC of the thymus. Comprehensive genomic testing played a crucial role in distinguishing MEC from ASC. This case highlights the importance of genetic testing in cases of uncertain primary origins and in differentiating between morphologically similar tumors.

Published: January 2025

AbstractBackgroundThe objective of this study was to evaluate anaesthesia care professionals' perceptions and attitudes regarding the implementation and advancement of digital solutions in perioperative care.MethodsAnaesthesia personnel working in public Swedish institutions where anaesthesia is administered were invited to respond to an online survey regarding their attitudes towards digitalization in the workplace and their perceptions of information provision and future digitalization within anaesthesia and surgical healthcare. Data were analyzed using descriptive statistics, independent‐samples Kruskal–Wallis tests, and post‐hoc pairwise comparisons.ResultsThe survey response rate was 64.0% (n = 627). Most respondents agreed/strongly agreed that digital solutions facilitate their work, the preoperative preparation, patient participation, and being involved in the patients' journeys throughout the perioperative care process. The majority also agreed/strongly agreed that digital solutions could make more patients adequately prepared before anaesthesia/surgery, reduce the number of non‐optimized patients, and adapt the perioperative process to the patients' individual needs, as well as lead to reduced costs for the healthcare provider and reduced cancelled anaesthesia/surgeries. However, there were statistically significant differences between responses in relation to age groups, where the largest differences were observed between respondents in the age groups 20–30 and 61–70 years and in relation to what part of Sweden respondents worked in, with the largest differences between respondents working in Southern Sweden and the middle part of Sweden.ConclusionSwedish anaesthesia personnel are confident that digital solutions may enhance the efficiency of care within the anaesthesia setting. However, varying perceptions on the benefits and necessity of digital solutions are indicated.
Psychedelic‐assisted treatment for substance use disorder: A narrative systematic review
Authors: Piper Theodore , Small Francesca , Brown Sam , Kelleher Michael , Mitcheson Luke , Rucker James , Young Allan H. , Marsden John 
Published: January 2025

AbstractBackground and aimsThis is the first systematic review of the extant literature on all major psychedelic‐assisted treatment for alcohol use disorder (AUD), tobacco use disorder (TUD) and other substance use disorders (SUD). We aimed to summarise the evidence for efficacy of psychedelic‐assisted treatment for AUD, TUD, and SUD; to evaluate its quality; and to offer recommendations for research.MethodsThis was a prospectively registered narrative systematic review of open‐label, randomised controlled trials (RCT), and observational studies of d‐lysergic acid diethylamide (LSD), mescaline, psilocybin, ayahuasca, ketamine, ibogaine and 3,4‐methylenedioxymethamphetamine (MDMA). Eligible studies had SUD outcome measures including craving, substance use, relapse, and remission. Study quality was evaluated using the Cochrane Collaboration Risk of Bias (RoB), and Cochrane Collaboration RoB in Non‐randomised Studies of Interventions tool. Certainty of evidence for RCTs was judged using the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) tool.Findings37 studies (2035 participants) were reviewed: LSD (14; n = 1047); mescaline (1; n = 7); psilocybin (4; n = 135); ayahuasca (3; n = 101); ketamine (10; n = 579); ibogaine (5; n = 166); and MDMA (1; n = 14). There were no serious adverse events reported in any study. A two‐centre, placebo‐controlled, phase 2 superiority RCT of psilocybin for AUD, and a two‐centre, double‐blind, four‐arm, placebo‐controlled phase 2 RCT of ketamine for AUD yielded the best evidence of efficacy. Progression support to a phase 3 trials was secured from an open‐label phase 2 study of psilocybin for TUD and nine phase 2 RCTs of ketamine for AUD, cannabis use disorder, cocaine use disorder, and opioid use disorder (all nine with high‐RoB and low‐GRADE evidence certainty).ConclusionsPsilocybin‐assisted treatment for alcohol use disorder appears to have the best evidence of efficacy among all major psychedelic‐assisted treatments for alcohol, tobacco, and other substance use disorders. Future research of psychedelic‐assisted treatment should report all safety events; screen for person‐level characteristics indicating that psychedelic‐assisted substance use disorders treatment is contraindicated; strive to mitigate blinding of participants to interventions; use factorial designs for drug and psychotherapy randomised controlled trials; and build consensus for a field‐specific Core Outcome Set.
