The Influence of the Extension Length of the Testing String on the Liquid Carrying Efficiency

Shiyou jixie, 2020
In the open-hole testing, the optimal testing string extension length is difficult to determine. Improper testing string extension length will cause problems such as long deliquification time and fluid accumulation in the bottom hole. For this reason, an

A Self‐Organized Liquid Reaction Container for Cellular Memory

Advanced Science, EarlyView.
How cells restore epigenetic information lost during replication is not known. This work proposes a mechanism based on the formation of biomolecular condensates. These condensates are induced by the chromosome itself and serve as reaction vessels for reconstructing missing epigenetic markers.

Numerical study on transient response of the bowed string

Mechanical Engineering Journal
This study focuses on the transient response in a bowed string with the stick-slip vibration for the clear understanding of its behavior and tone at the beginning of playing.

Evolution of FLRW spacetime after the birth of a cosmic string

, 2012
We consider the evolution of an initially FLRW universe after the formation of a long, straight, cosmic string with arbitrary tension and mass per unit length.

De Novo Multi‐Mechanism Antimicrobial Peptide Design via Multimodal Deep Learning

Advanced Science, EarlyView.
Current AI‐driven peptide discovery often overlooks complex structural data. This study presents M3‐CAD, a generative pipeline that leverages 3D voxel coloring and a massive database of over 12 000 peptides to capture nuanced physicochemical contexts.

Can cosmic strings generate large-scale streaming velocities?

The Astrophysical Journal, 1988
A detailed calculation is presented of the generation of large-scale streaming velocities by nonsuperconducting cosmic strings. A spherical infall model is used to calculate the peculiar velocity induced by an individual loop of cosmic string at rest in the comoving frame.

Connexin43 Deficiency Leads to Ventricular Arrhythmias by Reprogramming Proline Metabolism

Advanced Science, EarlyView.
The study demonstrated that connexin43 (Cx43) knockout caused arrhythmic phenotype and decreased proline content in vitro and in vivo. Mechanistically, Cx43 interacts with the amino acid transporter SNAT2 (sodium‐dependent neutral amino acid transporter), and its deficiency disrupts proline transport and metabolism.

The Use of Coiled Tubing as a Velocity String [PDF]

Acta Montanistica Slovaca, 2004
Liquid loading is a problem in many gas wells especially older and depleted type reservoirs. If steps are not taken to minimize this effect, it will severely limit the production or even "kill" the well.

Critical exponents of the driven elastic string in a disordered medium

, 2005
We analyze the harmonic elastic string driven through a continuous random potential above the depinning threshold. The velocity exponent beta = 0.33(2) is calculated.

A Perspective on Interactive Theorem Provers in Physics

Advanced Science, EarlyView.
Into an interactive theorem provers (ITPs), one can write mathematical definitions, theorems and proofs, and the correctness of those results is automatically checked. This perspective goes over the best usage of ITPs within physics and motivates the open‐source community run project PhysLean, the aim of which is to be a library for digitalized physics
