In this article, a circularly polarized dielectric resonator antenna (DRA) array with conformal characteristics and improved specific absorption rate (SAR) has been proposed for X-band applications. The proposed structure has been fed through the corporate feed network which excites a radiating mode inside DRA, i.e., $TE_{1\delta1}$. This mode has been utilized to enhance the impedance bandwidth which is below −10 dB for both the E- and H-plane so as to meet the requirements of next-generation defense communication and low-cost satellite systems. To generate the axial ratio (AR), the extended off-set feed has been employed to provide the required 90$^{\circ}$ phase shift. Further, in order to enhance the gain and reduce the SAR, an electromagnetic band gap structure has been used as a reflector. Furthermore, multiple arrays have been introduced to extend the coverage area through beam-forming. The proposed design has been fabricated for the experimental validation. The measured IBW and ARBW is 34.74% and 12.2%, respectively. The gain is 10.1 dBic throughout the band of operation along with the radiation efficiency above 85% in various bending conditions. The SAR is much below the permissible limit of 1.6 W/kg. Thus, the proposed array is compact, and it clearly achieves a smaller footprint, better IBW, ARBW and a low SAR with potential prospect for X-band purposes.

In this paper, we investigate a competitive market involving two agents who consider both their own wealth and the wealth gap with their opponent. Both agents can invest in a financial market consisting of a risk-free asset and a risky asset, under conditions where model parameters are partially or completely unknown. This setup gives rise to a nonzero-sum differential game within the framework of reinforcement learning (RL). Each agent aims to maximize his own Choquet-regularized, time-inconsistent mean-variance objective. Adopting the dynamic programming approach, we derive a time-consistent Nash equilibrium strategy in a general incomplete market setting. Under the additional assumption of a Gaussian mean return model, we obtain an explicit analytical solution, which facilitates the development of a practical RL algorithm. Notably, the proposed algorithm achieves uniform convergence, even though the conventional policy improvement theorem does not apply to the equilibrium policy. Numerical experiments demonstrate the robustness and effectiveness of the algorithm, underscoring its potential for practical implementation.

Cenobamate (CNB) has shown efficacy in reducing seizures in drug-resistant epilepsy (DRE) in clinical trials. We conducted a retrospective study at the Centre hospitalier de l’Université de Montréal epilepsy clinic to assess CNB’s real-world efficacy and safety. Among 109 patients, follow-up data were available for 68 at 3 months, 53 at 6 months and 54 at 12 months. Median seizure frequency reduction was 50.0%, 57.3% and 73.3%, respectively. Seizure freedom at 12 months was 25.9%. CNB was discontinued in 8.3% of individuals due to adverse events (non-serious) or treatment inefficacy. Our findings support CNB’s effectiveness in a DRE population.

This article examines the relational self-care practices of migrant Chinese women working as massage workers in the United States (hereinafter referred to as Chinese massage workers). Threading both the bodily and the intimate, Chinese massage workers offer care and relaxation for their clients through the modality of touch and quiet comfort. A wealth of scholarly work highlights the complexities of migrant massage workers’ daily lives and their paid labor of care. Thus far, the study of migrant massage workers focuses mainly on their romantic, familial, and work relationships. Little is known about the relational self-care practices that migrant massage workers engage in. Drawing on 20 months of ethnographic fieldwork, this article examines the practice of Chinese massage workers caring for one another through the intellectual genealogy of self-care in Black feminist scholarship. Through an examination of relational self-care performed by and for Chinese massage workers, this article shifts the focus from analyzing the expected performances of care-giving by migrant women massage workers within the economy of racial capitalism to a reconceptualization of self-care as a relational practice.

Emerging evidence has led to an interim review of the existing 2022 Canadian Stroke Best Practice Recommendations (CSBPR) for Acute Stroke Management, 7th edition, recommendations for endovascular treatment of acute ischemic stroke. This manuscript presents an update of the recommendations for endovascular treatment, addressing the issues of posterior circulation stroke, stroke with a large core and stroke with medium vessel occlusion (MeVO). These recommendations are a timely opportunity to reassess current processes to ensure efficient access to acute stroke diagnostics, treatments and management strategies, proven to reduce mortality and morbidity. These updated recommendations supersede the endovascular thrombectomy recommendations included in the 2022 publication of the CSBPR acute stroke management module. Additional materials to support timely implementation and quality monitoring of these recommendations are available at www.strokebestpractices.ca

The structural stability of barrier layers is critical for the long-term effectiveness of landfill remediation projects, although leachate pumping and organic contamination can cause structural degradation, reduce remediation performance, and increase the risk of pollutant release. The objectives of this study were to determine the consolidation–rebound mechanisms of sand–bentonite mixtures through standardized tests and to analyze deformation under diesel contamination using multi-scale approaches, including pore-structure characterization, particle-size distribution, cation exchange capacity, and oil-blocking effects. The results revealed that uncontaminated soil (0.0 wt.% diesel) exhibited non-linear compression behavior, with an initial decrease and a subsequent increase with increasing sand content; when the consolidation pressure exceeded 400 kPa, the compression rate decreased markedly. The compression deformation of the contaminated soil increased and was positively correlated with the sand and diesel contents, with accelerated deformation at >4.0 wt.% diesel. The rebound capacity decreased under combined sand–diesel effects. Microstructural analysis indicated that initial compression was controlled by inter-aggregate pores, whereas mid- to late-stage compression was influenced by intra-aggregate pore evolution and particle breakage. Increased diesel content shifted aggregate breakage from single/secondary to tertiary patterns, altering later compression behavior. Coupled hydration reduction and enhanced oil-blocking suppressed rebound significantly, worsening with increasing diesel content. Technical–economic analysis revealed that pure bentonite (0% sand) was optimal under uncontaminated conditions and that a 10% sand mixture was best under contaminated conditions. The sand–bentonite barrier exhibited amplified consolidation–rebound deformation and reduced stability with increasing sand and diesel contents, providing a theoretical basis for long-term landfill remediation assessment.

Longitudinal qualitative inquiry from a social gerontological perspective can offer unique insights into older adults’ wellbeing and home care service trajectories. This temporal case study of 12 older home care clients analysed 136 interviews over three time points with 53 home care network actors in Manitoba and Nova Scotia. Many clients and families grappled with service changes almost daily, even if the level or type of service appeared officially stable. The pandemic added further disruption, shaping clients’ lives, wellbeing, and relationships, as well as their access to and use of service. Notably, changes in clients’ wellbeing and needs for help were not necessarily straightforward nor always apparent to case coordinators, especially when these were tied to social, emotional, or relational wellbeing, or to clients’ living arrangements, housing, family, and community integration. Findings can enhance theorizing of change for older adults receiving home care and guide equity-informed policy and practice.

In this paper, we establish the $L^p$ bounds for partial polynomial Carleson operators along polynomial curves for $p \gt 1$, which depend only on $p$ and the number of monomials in the defining polynomial. Additionally, we study two classes of oscillatory integral operators of Radon type and derive uniform $L^2$ bounds.

To live meaningfully, we can’t just be receptacles for the right sorts of activities – it has to matter that it’s us living our lives. Something is missing in valuable activities, if the same value could be achieved by anyone who performs the task. Meaningfulness requires that it be our own ideals, personalities, and priorities contributing to the value of what we do. Recognizing this can shed light on our relationship with meaning in three ways. First, it shows a distinctive reason that autonomy is important: what we do without autonomy will lack meaning. Second, it helps us understand a challenge we encounter when facing trade-offs between different types of meaning, navigating between opportunities to have a few of our characteristics matter widely (e.g., as a filmmaker or an activist) and intimate contexts in which much more of who we are matters to a small group of people. Finally, if living meaningfully involves our central characteristics shaping what’s valuable about our actions, then discovering pre-set purposes (e.g., from fate, God, or the cosmos) might actually undermine our capacity to live meaningful lives.
