Optical neural networks: progress and challenges.

Artificial intelligence has prevailed in all trades and professions due to the assistance of big data resources, advanced algorithms, and high-performance electronic hardware. However, conventional computing hardware is inefficient at implementing complex tasks, in large part because the memory and processor in its computing architecture are separated, performing insufficiently in computing speed and energy consumption. In recent years, optical neural networks (ONNs) have made a range of research progress in optical computing due to advantages such as sub-nanosecond latency, low heat dissipation, and high parallelism.

Background: Peer support for chronic pain is increasingly taking place on social media via social networking communities. Several theories on the development and maintenance of chronic pain highlight how rumination, catastrophizing, and negative social interactions can contribute to poor health outcomes. However, little is known regarding the role web-based health discussions play in the development of negative versus positive health attitudes relevant to chronic pain.

November 2024
Department of Primary Care and Emergency Medicine, Kyoto University Graduate School of Medicine, Kyoto, Japan.
Importance: Current trauma-care protocols advocate early administration of fresh frozen plasma (FFP) in a ratio close to 1:1 with red blood cells (RBCs) to manage trauma-induced coagulopathy in patients with severe blunt trauma. However, the benefits of a higher FFP to RBC ratio have not yet been established.
Objective: To investigate the effectiveness of a high FFP to RBC transfusion ratio in the treatment of severe blunt trauma and explore the nonlinear relationship between the ratio of blood products used and patient outcomes.

We discuss the present state and planned updates ofCosmoLattice, a cutting-edge code for lattice simulations of non-linear dynamics of scalar-gauge field theories in an expanding background. We first review the current capabilities of the code, including the simulation of interacting singlet scalars and of Abelian and non-Abelian scalar-gauge theories. We also comment on new features recently implemented, such as the simulation of gravitational waves from scalar and gauge fields.
