Constraining chameleon field driven warm inflation with Planck 2018 data

European Physical Journal C: Particles and Fields, 2019
We investigate warm inflationary scenario in which the accelerated expansion of the early Universe is driven by chameleon-like scalar fields. Due to the non-minimal coupling between the scalar field and the matter sector, the energy-momentum tensor of ...

Dynamics of polynomial Chaplygin gas warm inflation

European Physical Journal C: Particles and Fields, 2017
In the present work, we study the consequences of a recently proposed polynomial inflationary potential in the context of the generalized, modified, and generalized cosmic Chaplygin gas models. In addition, we consider dissipative effects by coupling the

Genomic Insights into the Origin, High Fecundity and Environmental Adaptation of Hu Sheep

Advanced Science, EarlyView.
The Hu sheep diverged from the Small‐tailed Han sheep ≈1330 years ago, and subsequently migrated from northern to warm and humid southern regions. The genes BMPR1B, UNC5C, and GRID2 play a synergistic role in the superior reproductive traits of Hu sheep.

Role of trans-Planckian modes in cosmology

Journal of High Energy Physics, 2020
Motivated by the old trans-Planckian (TP) problem of inflationary cosmology, it has been conjectured that any consistent effective field theory should keep TP modes ‘hidden’ behind the Hubble horizon, so as to prevent them from turning classical and ...

Artificial Intelligence Is Stereotypically Linked More with Socially Dominant Groups in Natural Language

Advanced Science, EarlyView.
AI is not seen through an unbiased lens. People tend to stereotype AI as competent and link it with socially advantaged groups—such as men, the wealthy, the young, and prestigious occupations—raising concerns that such perceptions may deepen existing social divides rather than bridge them.

FOXM1 Protects Against Myocardial Ischemia‐Reperfusion Injury in Rodent and Porcine Models by Suppressing MKRN1‐Dependent LKB1 Ubiquitination

Advanced Science, EarlyView.
FOXM1 maintains mitochondrial bioenergetic function by inhibiting MKRN1‐mediated ubiquitination of LKB1 in cardiomyocytes. Loss of FOXM1 in cardiomyocytes results in upregulation of MKRN1, which enhances LKB1 ubiquitination and disrupts AMPK signaling and energy metabolism pathways. Conversely, FOXM1 overexpression preserves mitochondrial bioenergetics

Chaplygin gas inspired warm inflation and swampland conjectures through various scalar potentials

Chinese Physics C, High Energy Physics & Nuclear Physics
In this paper, we analyze inflationary parameters and swampland conjectures in the presence of a scalar field and Chaplygin models. We examine inflationary parameters, such as slow-roll parameters, scalar and tensor power spectra, spectral index, and ...

Prolonged Prophylactic Antibiotics Based on Preoperative Bile Culture Reduce Surgical Site Infections After Pancreaticoduodenectomy Following Preoperative Biliary Drainage: A Propensity‐Matched Analysis

Annals of Gastroenterological Surgery, EarlyView.
ABSTRACT Objective The optimum duration of prophylactic antibiotics after pancreaticoduodenectomy following preoperative biliary drainage to prevent surgical site infections remains controversial. We evaluate whether a prolonged course of prophylactic antibiotics reduces surgical site infection after pancreaticoduodenectomy following biliary drainage ...
