Published: February 2025

Abstract
MBenes, as emerging two-dimensional transition metal borides, have garnered significant attention in nanomaterials, but their application in memristors remains largely unexplored. This study focuses on chromium boride (CrB) in memristor fields, examining its structure and properties through first-principles calculations and simulating Ag ion diffusion within CrB layers. We fabricated an Ag/CrB/TiN memristor, which exhibited stable resistive switching and durability beyond 100 cycles. Our findings confirm the potential of CrB in memristor technology and provide theoretical and experimental support for the future applications of MBenes.

X-Ray/Radio Quasiperiodic Pulsations Associated with Plasmoids in Solar Flare Current Sheets

Published: February 2025

Abstract
Plasmoids (or magnetic islands) are believed to play an important role in the onset of fast magnetic reconnection and particle acceleration during solar flares and eruptions. Direct imaging of flare current sheets and the formation/ejection of multiple plasmoids in extreme-ultraviolet images, along with simultaneous X-ray and radio observations, offers significant insights into the mechanisms driving particle acceleration in solar flares. Here, we present direct imaging of the formation and ejection of multiple plasmoids in flare plasma/current sheets and the associated quasiperiodic pulsations (QPPs) observed at X-ray and radio wavelengths, using observations from the Solar Dynamics Observatory/Atmospheric Imaging Assembly, RHESSI, and the Fermi Gamma-ray Burst Monitor. These plasmoids propagate bidirectionally upward and downward along the flare current sheet beneath the erupting flux rope during two successive flares associated with confined/failed eruptions. The flux rope exhibits evidence of helical kink instability, with the formation and ejection of multiple plasmoids in the flare current sheet, as predicted in an MHD simulation of a kink-unstable flux rope. RHESSI X-ray images show double coronal sources (“looptop” and higher coronal sources) located at both ends of the flare current/plasma sheet. Moreover, we detect an additional transient faint X-ray source (6–12 keV) located between the double coronal sources, which is cospatial with multiple plasmoids in the flare current sheet. X-ray (soft and hard) and radio (decimetric) observations unveil QPPs (periods ≈ 10 s and 100 s) associated with the ejection and coalescence of plasmoids. These observations suggest that energetic electrons are accelerated during the ejection and coalescence of multiple plasmoids in the flare current sheet.
Search for Neutrino Signals Correlated with LHAASO Diffuse Galactic Emission
Authors: Li Wenlian , Huang Tian-Qi , Xu Donglian , He Huihai 
Published: February 2025

Abstract
The diffuse Galactic γ-ray emission originates from the interactions between cosmic rays and the interstellar medium or radiation fields within our Galaxy, where the production of neutrinos is also anticipated. Recently, the Large High Altitude Air Shower Observatory (LHAASO) reported measurements of diffuse γ-rays from the Galactic plane with energies ranging from sub-TeV to 1 PeV. Using 7 yr of publicly available IceCube track data with the full detector, we conduct a template search using the γ-ray flux map observed by LHAASO-KM2A as the neutrino emission template and perform a scan search of the Galactic plane. In the template search, a mild excess of neutrinos is observed in the Galactic plane with a pretrial (posttrial) significance of 1.9σ (1.1σ). The measured muon neutrino intensity at 25 TeV is

Exploring the Complex Heliotail Boundary by an Extended Level Set Approach
Authors: Onubogu C. , Opher M. , Kornbleuth M. , Tóth G. , Florinski V. 
Published: February 2025

Abstract
There is an ongoing debate regarding the shape of the heliotail. Studies have shown that the heliotail may be “comet-like,” extending for thousands of au. Some previous works defined the heliopause using magnetohydrodynamic variables, which only serve as an approximation to capture the heliopause in all directions. Here we use a level set method in our heliospheric model to constrain the location of the heliopause. The level set function, f
HP, is defined by boundary conditions, having a value of +1 at the inner boundary and −1 at the outer boundary. We find that the f
HP = 0 criterion, the standard heliopause definition used by other models to determine where solar wind and interstellar plasma meet, is impacted in the heliotail, where there is a broad mixing region of solar wind and interstellar medium plasma, by the nature of turbulent flows in the heliotail. We explore a different isosurface, defined by f
HP = 0.99, where the interface is composed of 99.5% solar wind and 0.50% interstellar medium. This determines the limits of the heliosphere by the region of solar wind flow that is minimally influenced by the interstellar flow. This region also contains magnetic field lines with at least one end anchored to the Sun. We obtain a split heliotail structure using the f
HP = 0.99 criterion.
Investigating the CREDIT History of Supernova Remnants as Cosmic-Ray Sources
Authors: Stall Anton , Loo Chun Khai , Mertsch Philipp 
Published: February 2025

Abstract
Supernova remnants (SNRs) have long been suspected to be the primary sources of Galactic cosmic rays. Over the past decades, great strides have been made in the modeling of particle acceleration, magnetic field amplification, and escape from SNRs. Yet while many SNRs have been observed in nonthermal emission in radio, X-rays, and gamma rays, there is no evidence for any individual object contributing to the locally observed flux. Here, we propose a particular spectral signature from individual remnants that is due to the energy-dependent escape from SNRs. For young and nearby sources, we predict fluxes enhanced by tens of percent in narrow rigidity intervals; given the percent-level flux uncertainties of contemporary cosmic-ray data, such features should be readily detectable. We model the spatial and temporal distribution of sources and the resulting distribution of fluxes with a Monte Carlo approach. The decision tree that we have trained on simulated data is able to discriminate with very high significance between the null hypothesis of a smooth distribution of sources and the scenario with a stochastic distribution of individual sources. We suggest that this cosmic-ray energy-dependent injection time (CREDIT) scenario be considered in experimental searches to identify individual SNRs as cosmic-ray sources.
Prospective Comparison of Clinical Outcomes After Bilateral Implantation of Diffractive Trifocal Extended Depth-of-Focus and Diffractive Trifocal Hydrophobic Intraocular Lenses
Authors: Nagy Zoltán Z. , Dorman Peter , Szalczer Szilard , Kiss Huba 
Published: February 2025

Purpose
To compare clinical outcomes for patients implanted with either FineVision HP or FineVision Triumf intraocular lenses (IOL) (Beaver-Visitec International, Inc) following cataract surgery.

Methods
Twenty-six patients bilaterally implanted with the HP IOL and 27 patients with the Triumf IOL were followed up for 6 months in a prospective randomized study. Refraction, uncorrected and corrected distance visual acuity (CDVA), uncorrected and distance-corrected intermediate visual acuity (DCIVA), and uncorrected and distance-corrected near visual acuity (DCNVA) were evaluated. Defocus curves and contrast sensitivity were also measured. Patient-reported outcomes were assessed using the National Eye Institute Visual Function Questionnaire 25, and adverse events were registered.

Results

Ninety-four percent of the eyes in both groups were within ±1.00 diopter (D) of spherical equivalent. All of the patients had 20/20 or better binocular CDVA in both groups and 96% and 100% had 20/25 or better binocular CDIVA in the Triumf and HP IOL groups, respectively, being reduced to 32% and 91.7% for DCNVA, respectively. Differences between groups were statistically significant from −2.00 to −4.50 D with better visual acuity outcomes for the HP IOL group (
P
< .01). Better monocular photopic contrast sensitivity was found for the Triumf IOL group at 12 and 18 cycles per degree (
P
< .01). There was a statistically significant increase of the overall composite score in both groups before and after surgery (
P
< .001). Spectacle independence was similar between groups for distance and intermediate vision but higher for the HP IOL for near vision (96% versus 75%). There were no adverse events related to the IOLs.

Conclusions
Both IOLs showed good and comparable distance and intermediate visual acuities but near vision was better for the HP IOL. This model provided higher spectacle independence for near vision.

Anthropomorphic service recovery: the panacea following service failure of automated CSAs
Authors: Dlodlo Nobukhosi 
Published: February 2025

Orientation: Automated customer service agents (CSAs) are not mere tools but social interaction entities with anthropomorphic traits capable of predicting consumer responses following unique online service failures scenarios.Research purpose: The study advances the discourse in how automated CSAs can seem more human, with acute understanding of shopper experiences. Thus, anthropomorphism remains an ineluctable ingredient preceding the alteration of shoppers’ trustworthiness perceptions via forgiveness.Motivation for the study: Selected anthropomorphic traits of automated CSAs could make shoppers personify these agents as endowed with human qualities such as humour and response empathy, thereby enhancing the trustworthiness of non-human computer social actors.Research design, approach and method: A scenario-based quantitative survey was distributed as a hyperlink, yielding 287 valid participants.Main findings: The SEM-PLS analysis demonstrated good model fit. The findings showed a significant effect between empathy and anthropomorphism with perceived trustworthiness. In addition, anthropomorphic CSAs provide a trust shield effect, reducing the loss of trust following a service failure. Consequently, shoppers are more willing to forgive the online retailer.Practical/managerial implications: The findings of this study could shape customers’ response mechanisms during failed interactions with automated CSAs, offering salient insights to adequately address service failures while tapping into the judicious utilisation of human-robot collaboration opportunities.Contribution/value-add: The study provides initial lenses for considering the social acting nature of automated CSAs. The positionality in this paper is that during a online service failure, humans pardon and are more trusting of a technological service agent that demonstrates anthropomorphic and humanist attributes.

Published: February 2025

Abstract
Globally, cancer is currently the second leading cause of mortality after cardiovascular disease. In terms of death, colorectal cancer (CRC) ranks second among the most common types of cancer. Forty percent–fifty percent CRC patients contain mutations in the colonic and rectal epithelial tissues that alter the expression of oncogenes, tumor suppressor genes, and genes related to DNA repair mechanisms. Kirsten rat sarcoma viral oncogene (KRAS) mutations are one of the most dominant mutations in CRC. One of the important members of the RAS family is KRAS. The impact of KRAS mutations leads to poor prognosis and survival of CRC patients and drives many research studies to explore potential therapeutics or target therapy for the KRAS mutant CRC. This review summarizes the current understanding of the pathological consequences of the KRAS mutations in the development of CRC and updates the recommended targeted drugs based on the increasing number of high-quality clinical trials. The review article also provides an overview of the challenges faced in treating KRAS-mutated cancer, highlights the possible mutated KRAS inhibitory drugs, along a discussion of their limitations and future trends.

Published: February 2025

Abstract

Introduction:
This study aimed to investigate the knowledge, attitudes and perceptions (KAP) of advance care planning (ACP) among specialist healthcare professionals (HCPs) in neurology, neuro-oncology and surgery.

Methods:
This was a cross-sectional study of HCPs in Singapore. A standardised questionnaire was developed using validated questionnaires from the international literature, concepts of the Theory of Planned Behaviour and consultation with multidisciplinary palliative care specialists. The 45-item questionnaire included sections on sociodemographics, ACP experience and practices, ACP Knowledge, ACP Attitudes, ACP Perceptions and ACP Engagement.

Results:
A total of 114 doctors, nurses and allied health professionals (AHPs) responded to the survey. Neurological, neuro-oncological and surgical HCPs generally have positive KAP towards ACP, but confidence to advocate for and conduct ACP could be improved. Doctors scored higher on KAP and intentions to engage in ACP as compared to nurses and AHPs. Significantly more doctors and nurses had attended formal ACP training than AHPs, while more doctors had conducted ACP conversations than nurses and AHPs. Attitudes towards ACP were independently and significantly associated with willingness to advocate for ACP, while perceptions of ACP, perceived relevance of ACP and readiness to engage in ACP were independently and significantly associated with both willingness and confidence to advocate for and to conduct ACP. The most common barriers to ACP among HCPs were disinterest or distress of patients and families and the lack of time.

Conclusion:
Enhanced ACP support, such as protocols, supervision and training, could improve ACP practice and engagement among specialist HCPs.

Published: February 2025

Abstract

Introduction:
Caring for dying patients is a quotidian responsibility within medicine. The aim of this study was to better understand how well a medical school’s curriculum and clinical exposure prepared students to cope with palliative care and improved their clinical confidence in palliative care medicine.

Methods:
This was a cross-sectional study. A modified version of the Bereavement/End-of-life Attitudes about Care of Neonatal Nurses Scale (BEACONNS) questionnaire was administered to students of clinical years from Yong Loo Lin School of Medicine, National University of Singapore, from June 2021 to April 2022. An overall comfort score (OCS), a composite marker of students’ comfort in participating in palliative care, was formulated from the summation of Likert-scale responses. A higher OCS denotes higher comfort with palliative care.

Results:
Of the 920 medical students of clinical years, 219 (23.8%) responded to the questionnaire. Across the clinical years, the percentage of students who felt unprepared to take care of palliative care patients and families was similar, with mean ± standard deviation OCS of 46.3 ± 12.6, 45.9 ± 9.4 and 44.9 ± 8.1 for years 3, 4 and 5 students, respectively. Prior experience in caring for dying relatives (P = 0.045) and knowledge of palliative care protocols and policies (P = 0.031) were significant positive factors in relation to improved OCS. Female gender was associated with higher OCS. Medical students recommended increased exposure to actual palliative care patients, rather than relying solely on simulated patients, to better equip them to care for patients at the end of life.

Conclusion:
Medical students expressed a lack of confidence in palliative care medicine regardless of their year of study, and felt that there was insufficient teaching and exposure to palliative care education.

Abstract:

PURPOSE:
To identify the possible predicting factors for developing astigmatism following penetrating keratoplasty, namely age, gender, laterality, preoperative indication for surgery, size of donor and recipient graft, and selective versus total sutures removal. Moreover, the duration of postoperative topical steroids use and if that surgery was the first graft or a redo surgery.

METHODS:
A retrospective cohort study which included data of patients who underwent penetrating keratoplasty at the University of Jordan Hospital. Multiple local and systemic perioperative risk factors were evaluated concerning developing postoperative astigmatism.

RESULTS:
Three hundred and ninety-two eyes were included. Of those, 38.8% developed postoperative significant astigmatism. Significant astigmatism postkeratoplasty was found to be affected by preoperative diagnosis with corneal dystrophy being the most common indication associated with significant postoperative astigmatism. Significant astigmatism was significantly correlated with long-term topical steroid use, longer follow-up duration, and the first keratoplasty (P < 0.001). No correlation was found between significant astigmatism, age, and the time of suture removal.

CONCLUSION:
Determination of the factors that influence the development of significant astigmatism is crucial. A long-term follow-up is necessary as the incidence of significant astigmatism increases with time.
Pseudo-trisections of four-manifolds with boundary
Authors: Fushida-Hardy Shintaro 
Published: February 2025

Abstract
We introduce the concept of pseudo-trisections of smooth oriented compact 4-manifolds with boundary. The main feature of pseudo-trisections is that they have lower complexity than relative trisections for given 4-manifolds. We prove existence and uniqueness of pseudo-trisections, and further establish a one-to-one correspondence between pseudo-trisections and their diagrammatic representations. We next introduce the concept of pseudo-bridge trisections of neatly embedded surfaces in smooth oriented compact 4-manifolds. We develop a diagrammatic theory of pseudo-bridge trisections and provide examples of computations of invariants of neatly embedded surfaces in 4-manifolds using said diagrams.
