Rock Breaking Mechanism and Experimental Study of Axe-shaped PDC Cutter
Shiyou jixie, 2022 Axe-shaped PDC cutter has more obvious rock breaking advantage than conventional PDC cutter. In order to analyze the rock breaking mechanism of the axe-shaped PDC cutter, the finite element simulation and test were used to conduct comparison and force ...

On models of weak interaction symmetry breaking by colour forces
Physics Letters B, 1983 Abstract Comments are made on models in which the Weinberg-Salam symmetry is broken by colour forces. In particular, we discuss the relevance of compositeness of quarks, leptons and new fermions (including a family of colour sextets).

Versatile vector tools for efficient protein screening across multiple expression systems
FEBS Open Bio, EarlyView.A unified vector toolkit enables rapid protein expression screening across E. coli, insect, and mammalian cells. A single primer pair amplifies the target gene, which is inserted into any vector via a standardized interface. This streamlined workflow eliminates repeated cloning steps, accelerating the identification of optimal expression conditions for

Aging Is a Key Driver for Adult Acute Myeloid Leukemia
Aging and Cancer, EarlyView.Acute myeloid leukemia (AML) is a classical age‐related hematologic malignancy, and a key driver of AML is aging, which profoundly regulates intrinsic factors such as genomic instability, epigenetic reprogramming, and metabolic dysregulation, and alters bone marrow microenvironment.

Chronobiology of Cancer: How Aging Fuels Oncogenesis at the Molecular Level
Aging and Cancer, EarlyView.This graphical abstract illustrates the key biological pathways linking aging with cancer development and progression. In the upper left, cumulative exposure to ultraviolet radiation, toxins, and reactive oxygen species (ROS) causes DNA damage and genomic instability, whereas age‐related decline in repair mechanisms, such as ATM/ATR, BER, and NER ...
