Principal controlling factors of oil and gas accumulation and key exploration targets in southwestern Tarim Basin

Shiyou shiyan dizhi
The Lower Cambrian Yuertus Formation and the Carboniferous Kalashayi Formation in the southwestern Tarim Basin have high-quality source rocks. The paleotectonic framework and evolution of fault activity are well aligned with the critical periods of oil ...

Extracellular Vesicles‐Based Biological Macromolecule Delivery Systems: Biogenesis, Characterization, and Emerging Clinical Applications

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Extracellular vesicles (EVs) are nanoscale membrane‐bound structures that play a pivotal role in intercellular communication by transporting bioactive molecules, including proteins, lipids, nucleic acids, and organelles, between cells. Originating from the endosomal pathway, EVs reflect the physiological and pathological status of their parent

Orchestrating the metastatic symphony: the role of extracellular vesicles in the epithelial–mesenchymal transition and pulmonary niche formation of breast cancer

Biological Reviews, EarlyView.
ABSTRACT The complexity of breast cancer (BC) lung metastasis lies in the capacity of tumour cells to interact efficiently with distant organs to promote colonisation, a process that involves the sophisticated coordination of inherent cellular plasticity and the remodelling of the distant microenvironment.

Vendian – Early Cambrian granites of the Krutorechensky complex (Northern Urals, Russia): protolith age, geodynamic conditions of generation and transformation

Геодинамика и тектонофизика, 2019
The Main Uralian fault (MUF) zone is a suture at the junction of the Urals and the East European platform (EEP). Its complex tectonic melange is still poorly studied.

Building phenotypic character matrices for phylogenetic inference: exploration of 35 years of practice

Biological Reviews, EarlyView.
ABSTRACT Recent methodological development in phylogenetic inference has focused predominantly on molecular data. However, renewed interest in other data types, particularly morphological data, has followed from the increased recognition of the power of total evidence and tip‐dating approaches, including fossil data, for inference of time‐scaled trees ...

Carrion ecology: concepts, interdisciplinary synthesis, and perspectives

Biological Reviews, EarlyView.
ABSTRACT Carrion is a ubiquitous resource in both terrestrial and aquatic ecosystems, yet it has long been overlooked in ecological research. Over the past two decades, studies on carrion and the many organisms that exploit it have flourished, revealing not only wide‐ranging ecological functions but also significance far beyond ecology.

Bijactions in Cataland [PDF]

Discrete Mathematics & Theoretical Computer Science, 2014
In this abstract, I will survey the story of two enumerative miracles that relate certain Coxeter-theoretic objects and other poset-theoretic objects. The first miracle relates reduced words and linear extensions, while the second may be thought of as ...
