Finite element analysis of bearing capacity and cracking failure in semi-flexible pavement materials

Materials Research Express
Semi-flexible pavement (SFP) materials are known for their outstanding rutting resistance; however, their applications to new pavements are limited due to uncertainties in their structural bearing capacity and cracking behavior.

Experimental investigation of ecological semi-flexible pavement with silica sand as a partial substitution of cement [PDF]

Al-Qadisiyah Journal for Engineering Science
The exploitation of locally available and abundant natural resources such as silica sand and its use as a supplementary cementitious material in the production of grout used in semi-flexible pavement (SFP) surfaces is of paramount importance in reducing ...

Generation of Self‐Organizing Macrovascular Constructs by Bioprinting Human iPSC‐Derived Mesodermal Progenitor Cells

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+

Tandem Duplication‐Driven Neofunctionalization of UDP‐Glycosyltransferases Shapes the Diversification of Triterpenoid Saponins in the Cucurbitaceae

Advanced Science, EarlyView.
We present a chromosome‐level genome assembly of Siraitia grosvenorii and, through comparative genomics, uncover a conserved UGT73 tandem array driving triterpenoid saponin diversification in Cucurbitaceae. Crystalized SgUGT73AM30 further reveals the regioselectivity mechanism underlying its catalytic activity.
