We present a unified approach to describing certain types of collective decision making in swarm robotics that bridges from a microscopic individual-based description to aggregate properties. Our approach encompasses robot swarm experiments, microscopic and probabilistic macroscopic-discrete simulations as well as an analytic mathematical model. Following up on previous work, we identify the symmetry parameter, a measure of the progress of the swarm towards a decision, as a fundamental integrated swarm property and formulate its time evolution as a continuous-time Markov process. Contrary to previous work, which justified this approach only empirically and a posteriori, we justify it from first principles and derive hard limits on the parameter regime in which it is applicable.

Patient advocacy is a duty for professional nurses; however, not all nurses are empowered to advocate for meeting patients' needs. Participation in labor unions may serve as a venue for nurses with limited institutional decision-making authority to advocate for patient needs; however, unionization can be a time-intensive and fraught process. This study examined how nurses participating in a new union in an urban United States hospital described their reasons for participating in a labor union during collective bargaining.

It is crucial to understand the glucose control within our bodies. Bariatric/metabolic surgeries, including laparoscopic sleeve gastrectomy (LSG) and Roux-en-Y gastric bypass (RYGB), provide an avenue for exploring the potential key factors involved in maintaining glucose homeostasis since these surgeries have shown promising results in improving glycemic control among patients with severe type 2 diabetes (T2D). For the first time, a markedly altered population of serum proteins in patients after LSG was discovered and analyzed through proteomics.

Rationale And Objectives: The expression of human epidermal growth factor receptor 2 (HER2) in gastric cancer is closely associated with its treatment outcomes and prognosis. This study aims to develop and validate a HER2 prediction model based on computed tomography (CT). Additionally, the study evaluates the robustness of the proposed model.

Aim: Compare the convergent and divergent viewpoints of early-stage postoperative patients with glioblastoma and their caregivers on end-of-life care planning in Taiwan.
Background: Decision-making capacity in patients with glioblastoma may be compromised as disease progresses, making early future care planning essential to ensure that the provided care aligns with patients' goals. However, within many Asian cultures, the tendency to avoid discussions about death can lead patients to feel hesitant about addressing end-of-life care options.

Cancer-related deaths primarily occur due to metastasis, a process involving the migration and invasion of cancer cells. In most solid tumors, metastasis occurs through collective cell migration (CCM), guided by "cellular leaders". These leader cells generate forces through actomyosin-mediated protrusion and contractility.
