Development and external validation of a three-stage model to predict live birth after fresh IVF/ICSI embryo transfer

Haoxuan Guo, Yanhui Liu, Juncheng Tong, Xiaoke Zhang et autres

Background Predicting live birth outcomes following in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) remains challenging. Most existing models are typically limited to single time-point data and lack integration of sequential clinical information, constraining their utility for personalized decision-making. Methods This retrospective multicenter study …

Late-Time Emergence of Dark Energy and Its Interaction with Dark Matter

Sibo Zhang, Weiqiang Yang, Supriya Pan, Olga Mena et autres

We present an interacting scenario between dark energy (DE) and dark matter (DM), where DE has an emergent nature, that means, DE was absent in the early universe but it becomes effective only at late times. We consider two specific emergent DE …

Do DESI-DR2 BAO data imply a coupling of dark matter and dark energy?

Weiqiang Yang, Sibo Zhang, Dinorah Barbosa, Marco Antonio Álvarez et autres

We revisit an interacting dark matter (DM) -- dark energy (DE) model characterized by the interaction function $Q = Γρ_x$, where $Γ$ is a constant coupling parameter and $ρ_x$ is the energy density of DE. This type of interaction is independent of …

Beyond dynamical dark energy: the role of dark sector interactions after DESI DR2

Weiqiang Yang, Sibo Zhang, Supriya Pan, Andronikos Paliathanasis et autres

Recent DESI DR2 observations have renewed interest in extensions of the $Λ$CDM cosmological model, particularly through indications of a time-varying dark energy equation of state. In this work, we investigate whether such deviations may also involve interactions within the dark sector. We …

Globally doubled methane emissions from nutrient-enriched rivers

Junfeng Wang, Xinghui Xia, Shaoda Liu, Sibo Zhang et autres

ABSTRACT Methane (CH4) accounts for about one-third of the current anthropogenic greenhouse gas-driven warming. Rivers, particularly those draining human-impacted landscapes, are important sources of CH4 to the atmosphere. Yet, effective mitigation of this important flux remains elusive due to the lack of …

When One-Parameter Dark Energy Makes Neutrinos Physical Again

Weiqiang Yang, Eleonora Di Valentino, Eric V. Linder, Sibo Zhang et autres

A puzzling implication of current data interpreted in the $Λ$CDM cosmology is the preference for a negative sum of neutrino masses. Moving to $w_0w_a$CDM brings an appreciable fraction of the neutrino mass posterior back to positive values, while the constant equation-of-state dark …

Contrasting effects of iron minerals on soil organic carbon stability in mangrove wetlands with different salinities

Haixiao Zhao, Qian Tan, Sibo Zhang, Wei Yang et autres

Abstract Background Iron (Fe) oxides are vital for the stability of soil organic carbon (SOC) in wetlands, yet their impact on SOC stability in mangrove wetlands with varying salinity levels remains unclear. In this study, the effects of hematite treatment on soil …
