Exploration and application of in-situ stress estimation method based on core disking phenomenon of boreholes

Dizhi lixue xuebao
Objective  Rock core disking is a typical phenomenon that occurs in environments with high in-situ stress. The geometric characteristics and section shape of rock disking are related to the state of in-situ stress, and the site where this phenomenon ...

In Situ Stress Prediction in Subsurface Rocks: An Overview and a New Method

Geofluids, 2021
Methods for determining in situ stresses are reviewed, and a new approach is proposed for a better prediction of the in situ stresses. For theoretically calculating horizontal stresses, horizontal strains are needed; however, these strains are very ...

Targeting TNBC: core–shell polycationic polyurea dendrimers with inherent anticancer activity

FEBS Open Bio, EarlyView.
Core–shell polycationic PURE dendrimers were tested in TNBC‐derived tumor models. Both formulations selectively targeted TNBC and effectively reduced tumor volume. PUREG4‐OEI48 suppressed tumor growth without detectable toxicity, whereas PUREG4‐OCEI24, despite showing efficacy, induced hepatic toxicity.

Study on the Method for Measuring Stress on Rock Mass Excavation Surface under Extremely High Stress Conditions

Geofluids, 2022
In view of the limitations of several existing stress measurement methods under extremely high stress conditions (stress−strength ratio σ/Rc>0.5), this paper proposes a slot relief method based on partial deformation recovery to measure rock mass surface

Differential regulation of ZFAS1 splice variants by endoplasmic reticulum stress in hepatocyte cell lines

FEBS Open Bio, EarlyView.
ZFAS1 is a lncRNA promoting cell proliferation and migration, exhibiting high expression in various cancers. It is conserved, widely expressed, and produces multiple splice variants with unclear roles. We identified several splice variants in hepatocyte models, and found that inhibiting or suppressing regulators of the unfolded protein response (PERK ...

Evaluating the Core-Based Stress Measurement in Mining Engineering—A Critical Review of the Diametrical Core Deformation Technique

Applied Sciences
Accurate determination of in situ stress is fundamental for the safe and efficient design of underground construction projects such as tunnels, caverns, and deep mining excavations. Conventional techniques—particularly overcoring and hydraulic fracturing—

Physician Stress During Electronic Health Record Inbox Work: In Situ Measurement With Wearable Sensors

JMIR Medical Informatics, 2020
Background Increased work through electronic health record (EHR) messaging is frequently cited as a factor of physician burnout. However, studies to date have relied on anecdotal or self-reported measures, which limit the ability to match EHR use ...
