MicroRNA‐Seq Analysis Reveals a Critical Role for miR‐222 in Bovine Intramuscular Adipogenesis via the DDIT4/mTORC1 Axis

Animal Research and One Health, EarlyView.
Schematic diagram illustrating how miR‐222 promotes bovine intramuscular adipogenesis by targeting DDIT4 to activate the mTORC1 signaling pathway. ABSTRACT Intramuscular fat (IMF) is a key determinant of beef quality, particularly with respect to tenderness, flavor, and juiciness.

Suppression of chatter marks in surface grinding by using dynamic damper.

Journal of the Japan Society for Precision Engineering, 1987
In order to suppress the chatter marks due to the tuning-fork mode vibration of surfacegrinding machines, which is caused by intermittent contact of the wheel and the workpieceduring grinding operation, several types of dynamic dampers are developed and their effectiveness is investigated experimentally. It was found that in all cases the amplitudes of

Toward a Greener Future: How and When Blockchain and Digitization Drive Green Finance

Business Strategy and the Environment, EarlyView.
ABSTRACT The COVID‐19 pandemic has significantly affected small‐ and medium‐sized enterprises (SMEs) and poses challenges in acquiring financing. Growing green investments require transformative infrastructure and innovative green financing solutions. Blockchain technology is ideal for delivering green environmental information because it provides real‐

A Comprehensive Review of Fault‐Current Limiter Technologies for Smart and Resilient Power Systems

Energy Science &Engineering, EarlyView.
This review compares superconducting, solid‐state, and hybrid fault‐current limiters (FCLs) for modern alternating current, direct current, and hybrid grids. It shows that optimal FCL selection depends on fault characteristics, network configuration, voltage level, protection coordination, and resilience requirements rather than on a universally ...

Performing history, negotiating patriarchy: Actressing as gendered labor and the fragmentation of womanhood in Chinese historical costume drama

Feminist Anthropology, EarlyView.
Abstract Gender inequality remains widespread in the film and television production industry, yet it is seldom examined in relation to backstage working environments. This article integrates on‐screen and off‐screen perspectives to investigate the working lives of Chinese actresses.

Chatter Detection and Identification Based on Mode Decompositions

Advanced Engineering Materials
To meet the demand for industrial production of calendering or rolling, it is necessary to detect the onset of chatter before chatter marks appear on the workpiece. Therefore, mode decomposition techniques (empirical, bivariate empirical, and variational)

Disturbance from restoration reseeding is associated with short‐term topsoil carbon loss and alters soil bacterial communities and functions in degraded alpine meadows of the Qinghai–Xizang Plateau

Grassland Research, EarlyView.
Restoration reseeding of degraded alpine meadows increased aboveground vegetation but was associated with short‐term topsoil carbon loss, coinciding with a microbial strategy shift from resident carbon‐preserving to carbon‐spending bacterial guilds. Abstract Background Restoration of degraded ecosystems is widely promoted as a nature‐based solution ...

Dynamic Performance Enhancement of a High‐Agility Hypersonic Mechanical System via a Learning‐Augmented Robust Control Architecture

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT The design of control systems for high‐agility mechanical systems operating in extreme environments is a significant challenge in nonlinear dynamics. This paper addresses the complex dynamic control problem of a hypersonic interceptor, modeled as a multi‐input multi‐output (MIMO) mechanical system characterized by strong aerodynamic cross ...
