Investigating the impact of imperfections around a wellbore on liner deformation during hydraulic fracturing

open access: yesFrontiers in Mechanical Engineering
It is essential to maintain the integrity of liner–cement–formation in the well completion and production stages. However, large liner deformations have been extensively experienced during hydraulic fracturing operations in carbonate formations.

PAK1 activation drives divergent resistance mechanisms to aromatase inhibition and tamoxifen in a luminal: A breast cancer model

open access: yesMolecular Oncology, EarlyView.
Breast cancer remains a major cause of cancer death in women, frequently developing endocrine therapy resistance. This study demonstrates that upregulated p21‐activated kinase 1 (PAK1) activity drives resistance to tamoxifen and long‐term estrogen deprivation in ER+ breast cancer models.

Prediction and Application of Pore Pressure in Guangming Structure Formation of Hetao Basin

open access: yesCejing jishu
To ensure drilling safety and optimize reservoir evaluation in ultra-deep and high-pressure formations of the Guangming structure in the Hetao basin, solve accidents such as overflow and collapse caused by inaccurate pore pressure prediction, and support

Paclitaxel induces NM2‐dependent cellular contraction through GEF‐H1 dissociation from microtubules and RhoA/ROCK activation in cancer cells

open access: yesMolecular Oncology, EarlyView.
Taxanes are widely used chemotherapeutics whose effects on cellular mechanics remain poorly understood. We show that paclitaxel induces rapid cellular contraction by promoting GEF‐H1 dissociation from microtubules and non‐muscle myosin II activation through RhoA/ROCK.

Empirical Formula for Estimating Collapse Pressure of Dented Sandwich Pipes

open access: yesJournal of Marine Science and Engineering
Deepwater sandwich pipes (SPs) offer high collapse resistance and thermal insulation, making them promising for hydrocarbon transport under high-pressure and low-temperature conditions.

Analysis of Collapse Pressure Performance of Ultra-High Pressure Perforating Gun under Different Blind Hole Depths

open access: yesShiyou jixie, 2021
For the blind hole depth, outer diameter ellipticity and wall thickness unevenness that affect the collapse performance of ultra-high pressure perforating gun, an ideal geometric model and a model with geometric defects of ultra-high pressure perforating

Extracellular matrix remodeling and immune reprogramming drive residual tumor progression of liver cancer after incomplete microwave ablation

open access: yesMolecular Oncology, EarlyView.
Incomplete microwave ablation (iMWA) of liver cancer triggers a biphasic progression in residual tumors. At Day 3, the microenvironment is characterized by acute inflammatory responses and extracellular matrix (ECM) remodeling. By Day 14, a profound shift occurs toward oncogenic signal transduction and immunosuppression, marked by macrophage ...

An empirical formula for predicting the collapse strength of composite cylindrical-shell structures under external pressure loads

open access: yesOcean Engineering, 2019
This paper derives an empirical formula for predicting the collapse strength of composite cylindrical-shell structures under external hydrostatic pressure loads as a function of geometric dimensions and layered angles, where the effects of initial ...

Unique circulating miRNAome signatures captured with distinct molecular states in Lynch syndrome and sporadic colorectal cancer

open access: yesMolecular Oncology, EarlyView.
Circulating microRNA profiles distinguish nonmalignant Lynch syndrome from cancer‐associated Lynch syndrome, sporadic colorectal cancer, and healthy controls. Age‐stratified analysis reveals disease‐specific regulatory states, and a six‐miRNA panel shows concordant separation in an independent colorectal tissue cohort.

The buckling and collapse behaviour of saddle-supported cylinders - Keynote Lecture [PDF]

open access: yes, 2003
Recent work by the present authors on the collapse conditions for horizontal cylindrical saddle supported storage vessels is described and reviewed. Attention is directed to a range of geometries, typically R/t < 200, where plastic collapse type failure ...
