Computadores y democracia económica [PDF]
Revista de Economía Institucional, 2008 El colapso del socialismo anteriormente existente obedeció a causas integradas en su mecanismo económico, que no son inherentes a todos los socialismos posibles. El artículo muestra que la teoría económica marxista, junto con la informática, proporciona el fundamento para adelantar un programa económico socialista viable y que el desarrollo de la ...

Advancing the Prediction and Understanding of Placebo Responses in Chronic Back Pain Using Large Language Models. [PDF]
Eur J PainABSTRACT Background Placebo analgesia is a widely studied clinical phenomenon, yet placebo responses vary widely across individuals. Prior research has identified biopsychosocial factors that determine the likelihood of an individual to respond to placebo, yet generalizability and ecological validity in those studies have been limited due to the ...

Temporal interface in dispersive hyperbolic media. [PDF]
NanophotonicsAbstract Spatial inhomogeneity, temporal modulation, and engineered anisotropy of parameters of electromagnetic media offer numerous opportunities for manipulating light–matter interaction over the past decades. Here, we investigate a scenario in which we deal with the temporal interface, hyperbolic anisotropy in the form of layered structures, and ...

Sparse matrix‐vector and matrix‐multivector products for the truncated SVD on graphics processors
Concurrency and Computation: Practice and Experience, Volume 35, Issue 28, 25 December 2023., 2023 Summary Many practical algorithms for numerical rank computations implement an iterative procedure that involves repeated multiplications of a vector, or a collection of vectors, with both a sparse matrix A$$ A $$ and its transpose. Unfortunately, the realization of these sparse products on current high performance libraries often deliver much lower ...
