Effects of Dietary Multi-Strain Probiotics on Growth Performance, Antioxidant Status, Immune Response, and Intestinal Microbiota of Hybrid Groupers ( ♀ ♂).

This study aims to examine the effects of the mixture of G1-11 and G1-33, isolated from the gut of hybrid groupers ( ♀ × ♂), on the host. The hybrid groupers were divided into a control (C, without any probiotics), (BC, 10 cfu/g), (EA, 10 cfu/g), compound (mix, a 1:1 mixture of and ), and positive reference group (P, , 5 × 10 cfu/L). Each group had four replicates, with 30 fish per replicate (53.

A new cross-domain prediction model of air pollutant concentration based on secure federated learning and optimized LSTM neural network.

As air pollution worsens, the fast prediction of air pollutant concentration becomes increasingly important for public health. This paper proposes a new cross-domain prediction model of air pollutant concentration based on federated learning (FL), differential privacy laplace mechanism (DPLA) and long and short-term memory network optimized by sparrow search algorithm (SSA-LSTM), named FL-DPLA-SSA-LSTM. Firstly, with FL, SSA-LSTM is used as local training model for each city and predicts air pollutant concentration.
