Tensiones residuales en cerámicas multicapa de Al2O3-ZrO2: naturaleza, evaluación y consecuencias sobre la integridad estructural

open access: yesBoletín de la Sociedad Española de Cerámica y Vidrio, 2006
This work studies the design and processing by slip casting of multilayered systems based on thick alumina and thin aluminazirconia layers. During cooling from the sintering temperature residual stresses may arise due to expansion associated to the ...

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Influencia del enfriamiento de la etapa de cocción sobre las propiedades mecánicas del gres porcelánico

open access: yesBoletín de la Sociedad Española de Cerámica y Vidrio, 2007
This study was undertaken to determine the influence of post-fire cooling on generation of residual stress and mechanical properties in porcelain tile. The test pieces were prepared and subjected to different types of cooling.

EOR mechanism of fracture oil displacement agent for ultra-low permeability reservoir

open access: yesEnergy Reports, 2023
Due to the low permeability, small pore throat, and poor pore connectivity of ultra-low permeability reservoirs, fracturing was required to improve the flow environment of oil in the reservoir during its development. The combination of fracturing and oil

Hippo pathway at the crossroads of stemness and therapeutic resistance in breast cancer

open access: yesMolecular Oncology, EarlyView.
Dysregulation of the Hippo pathway drives nuclear accumulation of YAP/TAZ, activating stemness‐related transcriptional programs that sustain breast cancer stemness and fuel therapeutic resistance across subtypes, underscoring Hippo signaling as a targetable vulnerability. Figure created and edited with BioRender.com.

NKCC1: A key regulator of glioblastoma progression

open access: yesMolecular Oncology, EarlyView.
Glioblastoma (GBM) progression is driven by disrupted chloride cotransporter homeostasis. NKCC1 is highly expressed in stem‐like, astrocytic, and progenitor cells, correlating with earlier recurrence, while overall survival remains unaffected. NKCC1 serves as a prognostic marker and potential therapeutic target, linking chloride transporter imbalance ...

Compressive residual strength of the pultruded glass-fiber composite after tension-compression fatigue

open access: yesComposites Part C: Open Access
We experimentally determined the decrease of residual compressive strength of the pultruded glass-fiber laminate after tension-compression cyclic loading. The adapted Arcan rig was used for tension-compression fatigue tests.
