Purpose: To report the 1-year motor and sensory outcomes for patients with acquired comitant esotropia managed with preoperative prism adaptation.
Methods: Patients entered a multicenter randomized prospective evaluation of prism adaptation before strabismus surgery. Prism responders were randomized to surgery with the target angle based on either the entry angle or the adapted angle of esotropia. Three hundred five patients (92 percent of cohort) completed 1-year postoperative follow-up.
Results: The overall motor success rate for all patients in the study was 74 percent. Prism responders operated on for the adapted esotropic target angle had a satisfactory motor outcome more often than those operated on for the entry angle, 90 percent compared with 75 percent (P = 0.04). Significant predictors of a satisfactory motor outcome after surgery were prism adaptation, female sex, and hyperopia greater than or equal to +3.00 D. Prism responders operated on for the adapted angle showed fusion of the Worth 4-dot at substantially more often than did those operated on for the entry angle, 75 percent compared with 60 percent (P = 0.12).
Conclusion: Prism adaptation significantly improves the 1-year motor outcome after esotropia surgery in prism responders. There is no increase in the number of overcorrections. These results confirm the value of allotting the extra time and potential expense needed for this technique.

This study investigates the flow field around a finite rectangular prism using both experimental and computational methods, with a particular focus on the influence of the turbulence approach adopted, the mesh resolution employed, and different subgrid length scales. Ten turbulence modelling and simulation approaches, including both 'scale-modelling' Reynolds-Averaged Navier-Stokes (RANS) models and 'scale-resolving' Delayed Detached Eddy Simulation (DDES), were tested across six different mesh resolutions. A case with sharp corners allows the location of the flow separation to be fixed, which facilitates a focus on the separated flow region and, in this instance, the three-dimensional interaction of three such regions.

Background: Telehomecare monitoring (TM) in patients with cancer is a complex intervention. Research shows variations in the benefits and challenges TM brings to equitable access to care, the therapeutic relationship, self-management, and practice transformation. Further investigation into these variations factors will improve implementation processes and produce effective outcomes.

Background: This mixed methods study identified needed refinements to a telehealth-delivered cultural and linguistic adaptation of Meaning-Centered Psychotherapy for Chinese patients with advanced cancer (MCP-Ch) to enhance acceptability, comprehensibility, and implementation of the intervention in usual care settings, guided by the Ecological Validity Model (EVM) and the Practical, Robust Implementation and Sustainability Model (PRISM).
Methods: Fifteen purposively sampled mental health professionals who work with Chinese cancer patients completed surveys providing Likert-scale ratings on acceptability and comprehensibility of MCP-Ch content (guided by the EVM) and pre-implementation factors (guided by PRISM), followed by semi-structured interviews. Survey data were descriptively summarized and linked to qualitative interview data.

Optical edge detection is a crucial optical analog computing method in fundamental artificial intelligence, machine vision, and image recognition, owing to its advantages of parallel processing, high computing speed, and low energy consumption. Field-of-view-tunable edge detection is particularly significant for detecting a broader range of objects, enhancing both practicality and flexibility. In this work, a novel approach-adaptive optical spatial differentiation is proposed for field-of-view-tunable edge detection.

The stress distribution within the struts of lattice metamaterials is non-uniform under compressive loads, with stress concentrations typically occurring at the node regions. Inspired by bamboo, this study proposes a type of body-centered cubic (BCC) lattice metamaterial with tapered prism struts (BCCT). The compressive behavior, deformation modes, mechanical properties, and failure mechanisms of BCCT lattice metamaterials are systematically analyzed using finite element methods and validated through compression tests.
