Band sorting based on global continuity of eigenvalues and topological properties of phononic crystals
Authors: Ao Lihong , Ramiere Aymeric 
Published: December 2024

Abstract
Band sorting is critical to obtaining physical properties from eigenvalues and eigenvectors that constitute the band diagram. We propose a band sorting method based on the global continuity and smoothness of the eigenvalues on the parameter space. Several strategies based on the connection between neighbor eigenvalues and how to sweep the parameter space are introduced to recognize level crossing degeneracies and level repulsion degeneracies. Eigenvectors are then reassigned to each band according to their corresponding eigenvalues. As an example, the band diagram of a 2D phononic crystal is sorted, and the group velocity and Berry curvature are compared before and after band sorting. The Berry curvature shows unexpected eigenvector discontinuities, indicating that our method based on the eigenvalues only is more reliable than methods based on the eigenvectors. Our proposed method is general and allows for studying the transport and topological properties of periodic materials.
Electromagnetic and optical properties of Na, Mg, and Al-adsorbed stanene nanoribbons: potential applications
Authors: Thanh Tung Nguyen , Phong Tran Cong , Ngoc Hoang Van 
Published: December 2024

Abstract
Density functional theory (DFT) combined with the Vienna ab initio simulation package (VASP) was used to investigate the electronic, magnetic, and optical properties of one-dimensional stanene nanoribbons (SnNRs) and Na, Mg, and Al-adsorbed SnNRs. The SnNRs, with a width of 10 Sn atoms and hydrogen-passivated edges, retained their hexagonal honeycomb structure after structural optimization. Both pristine and adsorbed SnNRs exhibit narrow band gap semiconducting behavior, with pristine SnNRs being non-magnetic and adsorbed SnNRs showing non-zero magnetic moments. Partial density of states analysis revealed multi-orbital hybridization contributing to the formation of π and σ bonds. Optical property analysis highlighted distinct differences between pristine and adsorbed systems, including optical anisotropy and wavelength-dependent absorption. These results indicate the potential of SnNRs for applications in optical information technology, sensors and photocatalysis.

Published: December 2024

Abstract
The $^{252}$Cf isotope produced at Oak Ridge National Laboratory is a promising target material for the synthesis of new superheavy nuclei through fusion reaction experiments. Within the framework of the dinuclear system model, the reaction systems with the $^{252}$Cf target and the $^{48}$Ca, $^{45}$Sc, $^{50}$Ti, $^{51}$V, $^{54}$Cr, $^{55}$Mn projectiles are investigated for the synthesis of new isotopes $^{295-297}$Og, $^{292-294}$119, $^{297-299}$120, $^{298-300}$121, $^{301-303}$122 and $^{302-304}$123. The decreasing trend of the maximal evaporation residue cross sections with the increasing proton number of the compound nucleus are discussed in the capture, fusion and survival stages. Additionally, the radioactive beam-induced reactions based on the $^{252}$Cf target are investigated to reach the predicted neutron shell closure $N$ = 184, with the maximal evaporation residue cross section predicted to be 21 fb for synthesizing $^{302}$Og. The predicted results fall below the current detection limitation, indicating the necessity for advancement in both accelerator and detection techniques, as well as exploration of alternative reaction mechanisms.

Published: December 2024

Abstract
General one-loop formulas for loop-induced processes gg/γγ → φ i φ j with φ i φ j = hh, hH, HH&#xD;are presented in the paper. Analytic expressions evaluated in this work are valid for a class of&#xD;Higgs Extensions of the Standard Models, e.g. Inert Doublet Higgs Models, Two Higgs Doublet&#xD;Models, Zee-Babu Models as well as Triplet Higgs Models, etc. Analytic expressions for one-&#xD;loop form factors are written in terms of the basic scalar one-loop two-, three- and four-point&#xD;functions following the output format of both the packages LoopTools and Collier. Physical&#xD;results can be hence evaluated numerically by using one of the mentioned packages. Analytic&#xD;results are tested by several checks such as the ultraviolet finiteness, infrared finiteness of the&#xD;one-loop amplitudes. Furthermore, the amplitudes also obey the ward identity due to massless&#xD;gauge bosons in the initial states. This identity is also verified numerically in this work. In&#xD;the applications, we present the phenomenological results for the investigated processes in the&#xD;Zee-Babu model as a typical example in this report. In particular, production cross-section for&#xD;the processes γγ → hh are scanned over the parameter space of the Zee-Babu Models.Content from this work may be used under the terms of the Creative Commons Attribution 3.0 licence.

Broadband transmitted wavefront detection based on multi-wavelength laser interferometric system with the hysteresis nonlinearity compensation control system
Authors: Wang Fang , Li Xueyuan , Han Sen 
Published: December 2024

Abstract
Existing methods typically used to detect transmitted wavefronts (i.e. the phase-shifting interferometer) operating at only a few specific wavelengths, to overcome this limitation and improve the accuracy of transmitted wavefront detection, a digital multi-wavelength laser interferometric system and a feedforward open-loop hysteresis nonlinearity compensation method are proposed in this paper. The laser interferometric system contains a light source system, a collimating system, an imaging system and a phase-shifting control system. The light source system contains five lasers, and five lasers are 473, 532, 632.8, 721, 1064 nm lasers, respectively. The physical table lookup analysis method is utilized as the compensation method to compensate the hysteresis nonlinearity of piezoelectric transducers. At the same time, the hysteresis nonlinearity compensation method is applied in the multi-wavelength laser interferometric system. The experimental results show that the displacement linearity error of piezoelectric transducer reaches 0.58 V and the linearity reaches 18.68% without compensation. After using the physical table lookup analysis method compensation, the maximum displacement error of piezoelectric transducer is reduced to 0.07 V and the linearity reaches 2.42% at the lookup number of 1000, which proves that the method can accurately compensate piezoelectric transducer’ hysteresis nonlinearity. At the same time, the multi-wavelength laser interferometric system with the feedforward open-loop hysteresis nonlinearity compensation method is applied successfully to detect the transmitted wavefront of a glue lens at various wavelengths. The experimental results show that the maximum predicting error at 532 nm reaches 0.003 and the maximum predicting error at 632.8 nm reaches 0.002, which prove that the physical table lookup analysis method can be applied in the multi-wavelength laser interferometric system to improve the accuracy of transmitted wavefront detection and the multi-wavelength laser interferometric system has certain practicability.

Published: December 2024

Abstract
Accurate prediction of fatigue life is vital in the design of aerospace components subjected to varying stress levels and loading frequencies. In the current research, machine learning (ML) models were developed to predict the fatigue life of AA2024-T6, a popular aerospace grade alloy, under different stress levels and loading frequencies. The aim was to reduce the reliance on expensive and time-consuming experimental fatigue testing. Stress-controlled fatigue tests were conducted, followed by fractographic analysis using a scanning electron microscope to assess failure mechanisms. It was observed that fatigue life decreases with increasing loading frequency, with failure modes transitioning from ductile at higher stress levels to a combination of brittle and ductile at lower stress levels. Three ML models namely Elastic Net, k-NN, and Random Forest were evaluated using the experimental fatigue results as input. The Random Forest model, optimized with an 85%-15% training-testing data split and nine decision trees, outperformed other models with a Root Mean Square Error (RMSE) of 101.62, Mean Absolute Percentage Error (MAPE) of 5.23% and an R-squared value of 1.0. Confirmation experiments validated the model, showing an average deviation of 7.57% between predicted and actual fatigue lives. These results highlight the potential of ML models to accurately predict fatigue life, offering a reliable alternative to tedious and costly experimental methods.

Published: December 2024

Abstract
During medical emergencies, effective management of waste is crucial to preventing the spread of infections, protecting healthcare workers, and ensuring the safety of the broader society. The recent COVID-19 pandemic has underscored the importance of waste separation for efficient waste management and public health protection. However, Nigeria’s situation has not been addressed by research investigation despite its potential to shape waste management policy implementation and citizen alignment. Therefore, the current study examines the waste separation behaviour of Nigerian residents during the pandemic, utilizing an extended Theory of Planned Behaviour framework. The authors achieve this by analyzing survey data from 726 residents in two highly populated cities (Lagos and Oyo states). All the latent variables in the theory of planned behaviour show a positive and significant effect on waste separation behaviour, with attitudes emerging as the strongest influence. Past behaviour positively correlates with the intention to separate waste. However, the results of perceived policy effectiveness indicate a significantly negative moderating effect on the relationship between intention and waste separation behaviour. This outcome suggests a continuous need for public enlightenment with greater focus on policy implementation and enforcement in Nigeria. Infrastructure for waste separation should receive more attention, as the absence of suitable waste segregation bins or disposal facilities weaken environmental policy implementation and Nigerians cultivation of waste separation behaviour. This study provides policy direction to enhance waste separation practices for day-to-day environmental safety and preparedness in the event of future health emergencies.

Abstract

Aims
The impact of systemic inflammation in acute myocardial infarction complicated by cardiogenic shock (AMI-CS) is still a matter of debate. The present ECLS-SHOCK sub-study investigates the association of C-reactive protein (CRP) levels with short-term outcomes in patients with AMI-CS.

Methods and results
Patients with AMI-CS enrolled in the multicentre, randomized ECLS-SHOCK trial between 2019 and 2022 were included. The prognostic impact of CRP levels on admission, as well as the effect of extracorporeal life support (ECLS), stratified by CRP levels, was tested with regard to the primary endpoint of 30-day all-cause mortality. In 371 patients with AMI-CS and available CRP level on baseline, the median CRP level was 18.0 mg/L. Patients with CRP levels in the highest tertile were older and less often resuscitated from cardiac arrest. The highest tertile (i.e. CRP &gt;61.0 mg/L) was associated with an increased risk of 30-day all-cause mortality compared with patients with lower CRP levels (lowest tertile: ≤5.0 mg/L) [adjusted odds ratio: 3.54; 95% confidence interval (CI) 1.88–6.68; P = 0.001]. The use of ECLS did not reduce 30-day all-cause mortality, irrespective of CRP levels on admission. The additional inclusion of CRP to the IABP-SHOCK II score was associated with a slight improvement of the prediction of 30-days all-cause mortality (area under the curve: 0.74; 95% CI 0.68–0.79).

Conclusion
Higher CRP levels were independently associated with the risk of 30-day all-cause mortality in AMI-CS. The additional inclusion of CRP to a validated CS risk score may further improve the prediction of short-term prognosis.
Delayed manifestation of severe coronary artery injury/stenosis associated with cavo-tricuspid isthmus ablation: a case report
Authors: Kang Honsa , Takemoto Masao , Watanabe Takanori , Hironaga Kiyoshi 
Published: December 2024

Abstract

Background
Radiofrequency ablation (RFA) procedures including cavo-tricuspid isthmus (CTI) ablation have proven to be safe and effective therapies for the treatment of many cardiac tachyarrhythmias. The incidence of coronary arterial injury (CAI) associated with RFA including CTI ablation is estimated to occur in &lt;0.1% of patients. Most instances of CAI occur during ablation procedures or within a few weeks after RFA.

Case summary
We report a case of delayed manifestation of CAI of the right coronary artery 1 year after RFA, likely associated with a CTI ablation. The coronary angiography and intravascular ultrasound images revealed significant stenotic lesions primarily consisted of heterogeneous fibrous plaques including few echolucent lesions that consisted of a relatively smaller lipid or necrotic core without echo-attenuated plaques consisting of a fibroatheroma with a necrotic core or pathological intimal thickening with a lipid pool, and corresponded to the site of the CTI ablation. The patient remained stable without any symptoms 6 months post-percutaneous coronary intervention at that site.

Discussion
Physicians should consider the possibility of CAI associated with RFA procedures involving ablation near the coronary arteries (CAs) in patients presenting with chest discomfort after RFA, even when the presentation is remote from the index procedure. Unanticipated anatomic variations can predispose to CAIs. Therefore, awareness of the relationship between CA course and anatomical ablation site before RFA may be important to prevent CAIs and improve procedural safety.
Preanalytical Sedimentation Effects on Hematological Tests
Authors: Gard Kenneth , Gunsolus Ian L 
Published: December 2024

Abstract

Introduction
Specimens suspected of errors related to low hemoglobin or changes in hemoglobin beyond that of clinically explained variations during hospital stays are frequently redrawn under the auspices that they are contaminated. When lack of an indwelling IV eliminates contamination as a possibility, evaluation of the specimen between the time of collection and testing should occur.

Methods
As part of a quality improvement project, we investigated the impact of sedimentation on collected blood specimens not immediately transferred to their respective tubes from a syringe. Each syringe of blood was allowed to stand in a vertical position on the transfer device. After 10 min, each syringe was divided into a bottom half and top half into fresh blood tubes, with half of the samples inverted prior to division. Samples were then analyzed for complete blood count.

Results
These results indicate that implementing an inversion of collected specimens prior to transferring will effectively eliminate variations related to sedimentation of blood.

Conclusions
Results highlight the importance of specimen handling after collection, including appropriate mixing to avoid erroneous results caused by erythrocyte sedimentation. Mixing syringes before transferring blood to collection tubes ensures a uniform sample and accurate result.
Load-to-strength ratio as an estimate of wrist facture after gastric bypass vs gastric banding
Authors: Jung Grace H , Zahedi Bita , Bouxsein Mary L , Yu Elaine W 
Published: December 2024

Abstract
Bariatric surgeries such as Roux-en-Y gastric bypass (RYGB) and adjustable gastric banding (AGB) lead to long-term deficits in bone density but are also accompanied by decreased weight, which may lower the impact force with falls. The aim of this study was to compare the long-term skeletal impact of RYGB and AGB using a biomechanical evaluation of load-to-strength ratio at the distal radius as a surrogate for wrist fracture risk. We conducted a cross-sectional study evaluating bone microarchitectural parameters and bone turnover in adults who received either RYGB or AGB surgery ≥10 yr ago (RYGB: n = 22; AGB: n = 23). Bone strength at the distal radius was estimated by microfinite element analysis from HR-pQCT. We used a single-spring biomechanical model to estimate impact force and then calculated load-to-strength ratio as a ratio of impact force to bone strength, with higher load-to-strength ratios representing a higher susceptibility to fracture. In multivariable analyses, the RYGB group had higher bone resorption marker C-telopeptide (CTX) levels, lower volumetric bone density, and worse cortical and trabecular microarchitectural parameters than the AGB group. Furthermore, estimated bone strength at the radius was lower in the RYGB group (3725 ± 139 N vs 4141 ± 157 N, p = .030), and the load-to-strength ratio was higher in RYGB group as compared with AGB (0.84 ± 0.04 vs 0.72 ± 0.05, p = .035), suggestive of higher propensity for wrist fracture. Taken together, these results indicate the long-term deleterious skeletal effects are more concerning with RYGB than AGB.

Abstract

Background
Benign breast disease (BBD) increases breast cancer (BC) risk progressively for women diagnosed with nonproliferative change, proliferative disease without atypia (PDWA), and atypical hyperplasia (AH). Leveraging data from 18 704 women in the Mayo BBD Cohort (1967-2013), we evaluated temporal trends in BBD diagnoses and how they have influenced associated BC risk over 4 decades.

Methods
BC risk trends associated with BBD were evaluated using standardized incidence ratios (SIRs) and age–period–cohort modeling across 4 eras—premammogram (1967-1981), precore needle biopsy (CNB) (1982-1992), transition to CNB (1993-2001), and CNB era (2002-2013).

Results
With a median follow-up of 15.8 years, 9.9% of women were diagnosed with BC (invasive and/or DCIS). From the premammogram era to the CNB era, we observed a significant increase in BC risk, rising from an SIR of 1.61 to 1.99. The proportion of proliferative BBD diagnoses (PDWA or AH) increased markedly over time (28.1%-49.7%), as did the proportion of DCIS events (11%-28%; χ2 P &lt; .001). Within specific BBD categories, the risk of invasive BC increased modestly.

Conclusions
Absolute risk of BC within BBD categories remained stable, but the relative risk of BC after BBD increased over time due to notable increases in higher risk BBD lesions, specifically PDWA and AH. These findings illustrate how evolving screening practices have changed the risk profile of BBD and should inform management strategies for patients with BBD in modern clinical settings.
Accepting Appreciation: Partner Perceptions and Major Non-NATO Ally Designations
Authors: Parker Tyler B 
Published: December 2024

Abstract
A diverse group of governments have accepted “Major Non-NATO Ally” (MNNA) status since the designation's establishment in the late 1980s. This United States (U.S.) designation signals friendship and facilitates cooperation, but it provides no formal security commitments. Why and when have U.S. partners accepted MNNA status? I argue that designees will accept the status when they are ready to acknowledge America's appreciation—a perceptual and relational concept that conveys gratitude absent guarantees. For some designees, untimely embrace of U.S. appreciation could negatively impact their relations with their societies and/or third-party states. For others, accepting appreciation would preclude forming a formal alliance with the U.S. I analyze published sources and incorporate interviews to compare Qatar, which accepted MNNA status in 2022, and the United Arab Emirates, which has not accepted the status as of late 2024. This article contributes to the literature on asymmetric security alignments by centering the Gulf governments and it provides a timely evaluation of an underexplored aspect of global alliance politics.

Abstract

Introduction:
Back pain (BP) is a complex heritable trait with an estimated heritability of 40% to 60%. Less than half of this can be explained by known genetic variants identified in genome-wide association studies.

Objectives:
We applied a powerful multi-trait and gene-based approach to association analysis of BP to identify novel genes associated with BP.

Methods:
Using phenotypes and imputed genotypes from the UK Biobank 500k dataset, we generated a multi-trait phenotype by combining 3 BP-related phenotypes: chronic BP, dorsalgia, and intervertebral disk disorders. We performed gene-based association analysis for 3 BP-related phenotypes and multi-trait phenotype. Conditional analysis was applied to account for the effects of genetic variants outside the gene. Finally, we replicated significantly associated genes using the FinnGen database.

Results:
We identified 32 genes associated with BP and replicated 16 of them. Thirteen genes were detected using the multi-trait phenotype. Seven of the detected genes, MIPOL1, PTPRC, RHOA, MAML3, JADE2, MLLT10, and RERG, were not previously reported. Several new genes are known to be associated with traits genetically correlated with BP or to be involved in pathways associated with BP.

Conclusion:
Using new powerful methods of association analysis, we identified 7 novel genes associated with BP. Our results provide new insights into the genetics of back pain.
