Unveiling Mexico's Demographic Transitions
Studies in Family Planning, Volume 56, Issue 4, Page 778-808, December 2025.Abstract This study examines Mexico's fertility transition (1930–2015) and how socioeconomic status (SES), geography, and indigeneity shaped reproductive behaviors. Using net fertility—the number of surviving children under five—we assess how prestige bias (adopting high‐status fertility norms) and conformism bias (aligning with local norms) influenced

A low complexity precoding based on weighted two diagonal iteration in massive MIMO system
Dianxin kexue, 2018 In massive MIMO systems,with the increase of the number of users and antennas,the complexity of the downlink zero forcing (ZF) precoding increases due to the existence of large matrix inversion.In order to reduce the complexity,an improved weighted two ...

Turing Jest: Distributional Semantics and One‐Line Jokes
Cognitive Science, Volume 49, Issue 5, May 2025.Abstract Humor is an essential aspect of human experience, yet surprisingly, little is known about how we recognize and understand humorous utterances. Most theories of humor emphasize the role of incongruity detection and resolution (e.g., frame‐shifting), as well as cognitive capacities like Theory of Mind and pragmatic reasoning.

Demographic Biases in Naturalistic Language Recordings in the CHILDES Database
Developmental Science, Volume 28, Issue 3, May 2025.ABSTRACT In recent years, the importance of estimating demographic biases in research has become apparent. Here, we provide a systematic review of the CHILDES database, the major source of naturalistic recordings of children's linguistic environment.

Engineering Reports, Volume 7, Issue 1, January 2025.ABSTRACT Due to the long transmission distance of the constellation network represented by the low‐orbit satellite system, the satellite‐to‐ground link is subject to large path loss and limited communication performance. This paper uses multi‐satellite and multi‐beam joint transmission technology to form a virtual multiplex network with ground multi ...
