Advanced Science, EarlyView.ABSTRACT Vascularization remains a major obstacle in tissue engineering. Here, we introduce a bioprinting strategy to generate centimeter‐scale, self‐organizing “mother vessel” constructs from iPSC‐derived hiMPCs. By optimizing bioink composition, printing was accomplished in a single‐step approach. Within one week, hiMPCs differentiated into both CD31+

Shear failure in rock using different constant normal load
, 1999 SEILDEL – HABERFIELD’s [1] work was based on the analysis of the regular triangular asperities and assumed that the asperities were rigid. They used normal stiffness shear stress (CNS) to measure the joint dilatation rate and extended the LADANYI ...

Laboratory tests on shotcrete-rock joints in direct shear, tension and compression
, 2005 A series of laboratory tests was performed on cemented shotcrete-rock joints to investigate the strength and stiffness of the interfaces, while simulating field conditions as close as possible.

The cohesive frictional crack model applied to the analysis of the dam-foundation joint [PDF]
, 2010 The mechanical behaviour of dam-foundation joints plays a key role in concrete dam engineering since it is the weakest part of the structure and therefore the evolutionary crack process occurring along this joint determines the global load-bearing ...

Mechanical Activation of Piezo1 Drives Osteoarthritis Through Kdm5c‐Mediated Epigenetic Silencing
Advanced Science, EarlyView.Excessive mechanical stress activates Piezo1, triggering Ca2+‐dependent cytoskeletal forces that deform the nucleus and reduce H3K4me3. Kdm5c demethylates H3K4me3 at Col2a1 and Runx3 promoters. Kdm5c knockout rescues degradation. Repurposed telmisartan directly inhibits Kdm5c, blocking this axis and showing disease‐modifying efficacy in mouse OA models

Strength of Rock-Like Specimens with Pre-existing Cracks of Different Length and Width [PDF]
, 2016 Discontinuities play a key role in the failure process of rock and rock mass. Small fractures can decrease the strength of rock while large-scaled joints can have a significant effect on the overall stability of rock mass (Eberhardt et al.

Advanced Science, EarlyView.A facile laser‐induced graphene–silver nanocomposite strategy enables ultrathin epidermal electrodes with low impedance, high conductivity, and excellent mechanical robustness. The porous LIG–Ag conductive network mechanically interlocked with SEBS provides stable, motion‐resistant biopotential monitoring, enabling high‐fidelity ECG, EMG, and EEG ...
