Objective Significant racial and ethnic disparities in maternal morbidity and mortality as well as gynecologic outcomes persist in the United States. The role of ambulatory care in obstetrics and gynecology (OBGYN), particularly in facilities that separate resident and attending care along payor (and de facto racial) lines, remains unclear. This study examines patient perspectives on payor-segregated health care delivery in an academic medical center (AMC) and opinions on possible integration.
Study Design This is a qualitative study conducted at a single AMC with payor-segregated resident and attending outpatient sites. Interviews focused on patient perception of experience and value in outpatient OBGYN care, perspectives on the segregated care model, and attitudes about integration. Patients participated in a 30-minute semistructured interview with recruitment continuing until thematic saturation was reached (October 2022–August 2023). Interviews were coded using an integrated approach with grounded theory; 12% of transcripts were double-coded (k = 0.86).
Results We interviewed 26 patients (16 from resident, 10 from attending site). Patients prioritized practical aspects such as clinic proximity and quality of clinician interaction. Most were unaware of the payor-segregated clinic system and disapproved upon learning about it. Opinions varied on topics of telehealth and continuity, indicating diverse patient needs. Notably, minoritized patients valued race and class concordance in clinical spaces. Patients generally supported care integration, conditional upon the preservation of aspects of care they valued.
Conclusion Successful OBGYN care integration requires meeting individual needs while ensuring diversity, safety, and community-oriented care, alongside access and convenience. Incorporating patient voices is crucial for aligning services with expectations and improving patient experiences.

Abstract
Background The Modified Naranjo Criteria for Homeopathy (MONARCH) inventory is a novel and useful tool for assessing the likelihood of a causal relationship between the homeopathic intervention and the ultimate clinical outcome.
Objectives To explain and elaborate on the use of the MONARCH inventory to improve its consistency of use and thereby elevate the overall quality and evidentiary value of homeopathy case reports.
Explanation and Elaboration Each of the 10 MONARCH inventory domains is explained and elaborated with the aid of references from published literature and hypothetical clinical situations. The MONARCH total score can range from −6 to +13; within that range, an arithmetic total of +6 is available from the scores of four critical domains, which should be given prominence in the overall consideration of causality. In reporting a clinical case, great importance should be placed on the narrative of the MONARCH evaluation process, domain by domain.
Conclusion The application of MONARCH allows us to evaluate the likelihood of a causal relationship between the intervention and the observed clinical outcomes in successfully treated cases, thereby augmenting their evidentiary value.
Nonfunctioning Ectopic Pituitary Adenoma: A Rare Case Report from Southern Asia
Authors: Hazra Darpanarayan , Chandy Gina Maryann , Chakraborty Indranil , Ghosh Amit 
Published: December 2024

AbstractEctopic pituitary adenoma (EPA) is an extraordinarily rare condition characterized by the presence of a pituitary adenoma outside the intrasellar region. Although EPA may share similarities with typical pituitary adenomas in morphology, radiological findings, immunohistochemistry, and hormonal activity, it can present with either nonspecific or specific endocrine symptoms. A 37-year-old female school teacher with persistent and worsening headaches underwent neuroimaging, which revealed a sizable extra-axial solid mass in the right parasellar region, extending into the cavernous sinus, base of the skull, and sphenoid sinus. This mass was initially indicative of a cavernous sinus meningioma. Laboratory investigations, including a pituitary hormone profile, yielded normal results. Despite the lack of typical symptoms, the patient underwent an elective right temporal craniotomy and subtotal tumor resection, which exposed both extra-axial and intra-axial components. Immunohistochemistry analysis confirmed the presence of a pituitary adenoma with atypical features. Postoperatively, the patient recovered well, and adjuvant stereotactic radiosurgery was used to address the residual lesion. During the 1-year follow-up, the patient remained free of symptoms. This case highlights the diagnostic complexities associated with nonfunctioning EPAs and underscores the importance of a comprehensive approach to ensure accurate diagnosis, effective treatment, and sustained patient well-being.
Formation of a step on the surface of a crystal as a result of the emergence of an edge dislocation from the bulk and growth-step motion on the surface of a quantum crystal
Authors: Kosevich A. M. , Kosevich Yu. A. 
Published: December 2024

The formation of a step on the surface of a crystal as a result of the emergence of an edge dislocation is discussed. The description of the dislocation in the theory of elasticity is shown to be consistent with the description of the step in the theory of surface tension. It has been established that a step on the surface can break off, ending in a screw dislocation that emerges on the surface: when discussing the processes of the formation of steps on a surface it is necessary to take account of a reaction of the step ⇄ dislocation type.
Attention is drawn to the fact that the crystallization-melting wave can be represented as the directed motion of a large number of growth steps on the surface of the quantum crystal.
The dynamics of steps has been considered and the effective mass of an individual step has been calculated. A correction has been found to the dispersion relation for Andreev–Parshin surface waves.
Spin diffusion in spin-polarized quantum crystals
Authors: Piradashvili I. N. 
Published: December 2024

Within the framework of the Hubbard model with an almost half-filled energy band we consider the scattering of a delocalized vacancy (vacancion) from spin fluctuation in a completely polarized system. For a simple cubic lattice and a planar square lattice we have obtained the exact value of the scattering amplitude. For “inelastic” scattering (with a shift of the flipped spin) the cross section in the long-wave limit of the three-dimensional problem does not depend on the quasimomentum of the vacancion. In the two-dimensional case the “υ−1 law” is satisfied for the cross sections. For the case of vacancion scattering from an isotopic impurity we show that bound states can exist.
The temperature dependence of the spin diffusion coefficient is explained for the case of thermally activated vacancies and for low temperatures with a given vacancy concentration.
One-dimensional spin glass with large-radius oscillating interaction
Authors: Ioffe L. B. , Feigeľman M. V. 
Published: December 2024

We consider the model of a spin glass with the interactions SiVijSj, Vij = γ cos(qrij)e−γrij. This model is equivalent to the problem of a charge-density wave being pinned by the potential of interaction with an impurity, V = T In cosh[T−1 2ρ cos(φ + qxi)], where φ is the phase and xi is the position of the impurity. Investigation of the pinning of such a charge-density wave at times much longer and much shorter than the time of the pinning breaking has made it possible to obtain the physical quantities (specific heat and susceptibility) of the initial model of spin glass.
In the region of the lowest temperatures the susceptibility depends strongly on the time of the measurement, is constant in the “field cooling” regime, and vanishes exponentially [exp( − 2πγT−)] with the usual measuring technique.
Influence of quantum effects on the brittle–ductile transition in cryocrystals
Authors: Leont’eva A. V. , Romanusha V. A. , Feľdman É. P. 
Published: December 2024

We have studied the properties of ductility, strength, and the brittle–ductile transition (BDT) in inert Ne, Ar, Kr, and Xe cryocrystals. A theoretical model of the BDT, which makes it possible to estimate the value of the BDT barrier, is proposed.
It is shown that for cryocrystals with a considerable contribution of the energy of zero-point vibrations to the binding energy a quantum correction must be introduced, using an effective temperature that is proportional to the rms displacements.

Published: December 2024

We developed a wideband RF cavity beam position monitor (CBPM) with a 217 MHz bandwidth centered at the 4.875 GHz dipole mode frequency as part of the preliminary research for a high-repetition-rate hard x-ray free electron laser project at the Chinese Academy of Engineering Physics. This paper presents new results demonstrating bunch-by-bunch position measurements on electron bunches spaced by 2.3 ns (4 bunches per train). Over a measurement range of ∼100 μm, this wideband CBPM achieved a spatial resolution of 0.8 μm at a bunch charge of 80 pC. Position and tilt variations between bunches on the order of 10 μm and 10 μrad, respectively, were clearly resolved. This high spatial and temporal resolution provides a valuable tool for experimental studies on long-range wakefield effects in multi-bunch operational light sources.
Indexing a withdrawal from one’s previously-taken position
Authors: Zhang Shuling , Qiu Mengying 
Published: December 2024

Abstract
Using conversation analysis as the research method, this article investigates what participants do with the
multiple saying duì duì duì (‘right right right’) when they take divergent positions in Mandarin Chinese
conversation. A participant may deploy duì duì duì to claim recalibrating understanding, which indexes a backdown
or withdrawal from a previously-taken position. There are two trajectories to make such concessions. One is “Claim X — Concession
(duì duì duì) — Claim Y”, with Y taking the co-participant’s perspective into account and duì duì
duì serving as a pivot for the new Claim Y. The other is “Claim X — Concession (duì duì duì)”, in
which conceding means abandoning. Through these trajectories, participants find out something different and implicate that their
prior action is problematic due to not taking something into account, so they concede and change. This article will contribute to
both concession and multiple sayings studies.
Effects of indirect corrective feedback and teacher encouragement on EFL students’ writing accuracy
Authors: Fan Ning , Ma Yingying 
Published: December 2024

Abstract
This study examines the effects of indirect corrective feedback and positive affective teacher comments on English
as a foreign language (EFL) students’ writing accuracy in new writings and revisions. Four intact classes of EFL students
(n = 231) were randomly assigned to four groups: (1) Indirect-coded corrective feedback (ICCF), (2) ICCF +
positive teacher comments, (3) Indirect non-coded corrective feedback (INCCF), (4) INCCF + positive teacher comments. Two-way
factorial ANOVAs investigated the effects of indirect CF (ICCF or INCCF) and the presence or absence of positive teacher comments
on students’ writing accuracy in new writings and in revisions. Results revealed that, beginning with similar levels of writing
accuracy and attitudes toward writing feedback, groups provided positive teacher comments significantly outperformed the groups
not provided positive comments in both new writings and revisions. There was no significant difference for the type of corrective
feedback provided, nor was there a significant interaction effect. This study provides evidence that teacher encouragement through
positive affective comments can have a significant impact on students’ writing acquisition. The paper concludes with implications
for EFL writing instruction.
Rebranding Unsustainable Destinations: The Case Study of Miami Beach Breaking Up with Spring Break
Authors: Spezzano Walter , Lusby Carolin 
Published: December 2024

Summary

Spring break has long been a double-edged sword for destinations, especially in Florida, United States, where cities gain economic benefits while facing significant challenges that impact the safety and sustainability of these areas. This case study examines the strategic response of Miami Beach to the negative impacts of spring break, including overcrowding, rising crime rates, and disruption to community life, which led to states of emergency in 2021, 2022, and 2023. To face these issues, the city government, in collaboration with the local destination marketing organization (DMO), crafted a strategy that included the
Miami Beach Is Breaking Up With Spring Break
marketing campaign. This campaign utilized a breakup metaphor to communicate the city’s firm stance against unruly tourist behavior. Through rebranding, Miami Beach aimed to redefine itself as a calmer, safer, and more community-focused destination, prioritizing the well-being of both residents and visitors. The campaign effectively conveyed this message by combining emotional narratives with persuasive language, contrasting disruptive behavior with the city’s core values. This case highlights the role of storytelling in destination rebranding as a tool to address tourism-related challenges, fostering long-term sustainability and community well-being.

Suppression of hyperuniformity in hydrodynamic scalar active field theories
Authors: Padhan Nadia Bihari , Voigt Axel 
Published: December 2024

Abstract
The coarsening dynamics at late times in phase-separating systems lead to universally hyperuniform patterns. This is well known for scalar field theories, such as the Cahn–Hilliard equation, but has also been shown for dry scalar active field theories. We demonstrate the role of hydrodynamic interactions in influencing hyperuniformity in a wet active system described by active model H. Our direct numerical simulations reveal that, while (passive) model H shows hyperuniformity in the coarsening regime, the interplay of activity and hydrodynamic interactions suppresses hyperuniformity in active model H, especially when the activity generates contractile stress in the fluid.

Published: December 2024

Abstract
MXenes [two-dimensional (2D) transition-metal carbides, nitrides and carbonitrides] are gaining significant interest as alternative electrocatalysts for the hydrogen evolution reaction due to their excellent properties such as high electrical conductivity, large surface area and chemical stability. MXenes are traditionally synthesized using hydrofluoric acid (HF), which raises safety and environmental concerns due to its highly corrosive and toxic nature. HF introduces fluoride functional groups on the surface of MXenes, and these have been reported to have a detrimental effect on electrocatalysis. As a result, there is growing interest in developing MXenes through non-fluoride routes. Here, we report room-temperature, HF-free, wet-chemical synthesis of MXene using a mixture of hydrogen peroxide and chromium chloride. The newly prepared CH-MXenes possess hydrophilic functionalities (–Cl, –OH and =O). Key advantages of the CH route over HF-based synthesis include the elimination of an additional delamination step, the prevention of MXene restacking via chloride functionalities and the consistent production of high-quality 2D MXenes with a reproducible flake size (∼650 nm). These CH-MXenes exhibit a high surface area, excellent conductivity and enhanced chemical stability, making them suitable for various energy and other applications.

Published: December 2024

Abstract
In this research, the fluid plasma transport code SOLPS-ITER is applied and validated against experimental data from the plasma interaction surface component experimental station (PISCES)-RF linear plasma device to establish a physics basis for plasma and neutral transport in its two magnetic field (B-field) geometry setups-(1)the cusp and (2) non-cusp or linear B-field. The main focus of this study is to understand (1) radial plasma transport (2) heat and particle loads on the upstream dump and downstream target plate, and (3) the physics of plasma-neutral interactions in PISCES-RF. The simulation setup adheres to typical PISCES-RF experimental conditions, with a 2D helicon power deposition profile as an input heating source. SOLPS-ITER simulations reproduce experimental conditions with the Bohm diffusion model for both B-field configurations of the PISCES-RF experiment. Major energy loss channels include neutral radiation and power deposited on the wall and dump plate, with only 1

%

of the input power reaching the target. The ionization front is well confined near the dump plate due to the heating and puffing regions. Additionally, SOLPS-ITER simulation results are also found to be in very good agreement with the particle-in-cell calculations using the code-PICOS++ which supports the validity of SOLPS in low collisionality regime.

Abstract
The symmetry diagnosis of the implosion process can reflect the compression evolution, as well as laser ablation symmetry and hydrodynamic instability, which is a significant research topic for improving implosion performance in inertial confinement fusion (ICF). The wide-angle velocity interferometer system for any reflector (VISAR) has the ability to diagnose three-dimensional implosion compression. However, the preheating phenomenon limits the applicability of wide-angle VISAR. This work developed a radiation hydrodynamics simulation model of wide-angle VISAR preheating to investigate the effect of various parameters on diagnostic system performance. It specifically investigates the impact of ablator layer thickness, shielding thickness, laser energy, and M-band x-ray radiation fractions on the wide-angle VISAR. The results indicate that excessively thin ablator and shielding layers result in the preheating of the ellipsoidal mirror. The increased peak radiation temperature shifts the energy spectrum into the M-band region, causing the ellipsoidal mirror to be preheated and melted, and the wide-angle VISAR to lose its diagnostic capability. Indirect drive implosion experiments were carried out to verify the simulation results. When the peak radiation temperature is 160 eV, with insufficient thickness of the ablator layer and the shielding layer, the shock wave enters the CH layer for 0.50 ns, and the ellipsoidal Al mirror will be completely melted. However, the current wide-angle VISAR can obtain velocity information at lower drive energy. In the future work, it is planned to shield the preheating effects, which will be helpful to promote the application of wide-angle VISAR for 3D symmetry diagnostics under high radiation temperature conditions and ultimately provide an important diagnostic tool for ICF.
Heat flux mitigation characteristics in the radiative divertors with multi-peaks of heat flux in the large helical device
Authors: Hayashi Yuki , Masuzaki Suguru , Kobayashi Masahiro , Kawamura Gakushi , Mukai Kiyofumi , Tanaka Hirohiko , Murase Takanori 
Published: December 2024

Abstract
In this study, the effects of impurity seeding on the one- and two-dimensional heat flux profiles of the large helical device divertor with a multi-peaks of heat flux were investigated, focusing on the heat-flux-reduction characteristics at the two peaks. The divertor heat flux profile was reconstructed using finite element analysis based on the temperature distribution measured via infrared thermography. The divertor heat flux profiles were calculated using the EMC3-EIRENE code considering the impurity seeding. In general, the calculated results were consistent with the experimental observations, including the heat flux value and reduction via impurity seeding. The reduction in the divertor heat flux due to impurity seeding was almost similar at different heat flux peaks and exhibited little dependence on the heating power variance. The difference between the low- and high-heating-power cases is discussed by tracing the magnetic field lines from the divertor plate and considering the penetration depth of the impurity particles into the scrape-off layer plasma.
A novel angle sensitive rotary magnetorheological damper

Published: December 2024

Abstract
Traditional shear type rotary magnetorheological (MR) dampers have a constant working gap in the activation zone, and the damping force output is only controlled by the excitation current. By combining with closed-loop control algorithms and devices, variable damping force output can be achieved. However, this closed-loop control system is complex and requires additional control equipment. If the control system fails, it is impossible to achieve the output of damping force changes, which is unacceptable in some extremely high reliability, low-cost, and narrow space working conditions. In order to achieve variable damping force output of the rotary MR damper throughout the full piston stroke under constant excitation current, a novel variable positional damping rotary MR damper (VPD-RMRD) is proposed in this study. By presetting the size of the activation gap between the piston and cylinder at different angular positions, it is possible to achieve damping force variation output throughout the entire piston stroke without the need for additional control devices. This variable damping output method only requires a constant excitation current. The prototype of VPD-RMRD has been manufactured and subjected to performance testing. In order to verify the feasibility of applying VPD-RMRD to vibration reduction, this study applied it to the seat suspension system. The experimental results show that the maximum reduction in acceleration transmission rate is more than 20%. The proposal of VPD-RMRD provides a new solution for vibration reduction in narrow spaces, high reliability, and low-cost operating conditions.
