Effect of Drying and Wetting Cycles on the Surface Cracking and Hydro-Mechanical Behavior of Expansive Clays

open access: yesBuildings
Expansive clays present serious issues in a variety of engineering applications, including roadways, light buildings, and infrastructure, because of their notable volume changes with varying moisture content.

The PI3Kδ inhibitor roginolisib (IOA‐244) preserves T‐cell function and activity

open access: yesMolecular Oncology, EarlyView.
Identification of novel PI3K inhibitors with limited immune‐related adverse effects is highly sought after. We found that roginolisib and idelalisib inhibit chronic lymphocytic leukemia (CLL) cells and Treg suppressive functions to similar extents, but roginolisib affects cytotoxic T‐cell function and promotion of pro‐inflammatory T helper subsets to a

Numerical prediction of crack formation in historic masonry buildings

open access: yesMagazine of Civil Engineering
This article investigated mechanical behavior of the masonry of historic buildings. It was assumed that reliable cracking processes can be obtained by modeling masonry as a continuous medium and using the Jointed Masonry Model (JMM).

Line Spring Model and Its Applications to Part-Through Crack Problems in Plates and Shells [PDF]

open access: yes
The line spring model is described and extended to cover the problem of interaction of multiple internal and surface cracks in plates and shells. The shape functions for various related crack geometries obtained from the plane strain solution and the ...

Effect of Notches on the Axial Fatigue Properties of Structural Steels [PDF]

open access: yes, 1963
The effect of the stress concentration on the zero-to-tension axial fatigue strength of notched members of four structural steels has been studied. For each of the four steels a critical notch severity was found at which a transition in behavior takes

ON CRACK CLOSURE IN FATIGUE CRACK GROWTH

open access: yes, 1978
A brief review of the various forms of closure is given, and the relative importance of plasticity-induced closure and roughness-induced closure is considered. On the basis of the lack of a thickness effect and an insensitivity to R in the absence of closure it is concluded that plasticity-induced closure plays a relatively minor role in affecting the ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Cotargeting TREM2 and IL2 pathways triggers multipronged anticancer immunity

open access: yesMolecular Oncology, EarlyView.
Von Locquenghien et al. report that MiTE‐144, a triggering receptor expressed on myeloid cells 2 (TREM2) blocking antibody fused to interleukin‐2 (IL2) variant with tumour microenvironment restricted activation, demonstrates superior anticancer efficiency in a preclinical setting.

Fissure evolution and variation of pyrolysis kinetics parameters of tar-rich coal during heat treatment under different atmosphere

open access: yesMeitan kexue jishu
The clean and efficient development of tar-rich coal is helpful in ensuring China's energy security. The tar-rich coal from Ningtiaota Mine was selected and heated under N2 and hypoxia atmosphere.

Crack growth criteria and crack tip models

open access: yes, 1988
Summary: The current status of crack tip characterizations is reviewed. Several unresolved areas for further research are identified. Singular fields for stationary and moving crack tips in different nonlinear materials are reviewed and special emphasis is put on the extension of the region where these fields dominate.
