Research on time-dependent behavior of rock-socketed pile group based on FEM-BEM coupling method

Yantu gongcheng xuebao
For time-dependent behavior of rock-socketed pile groups, the finite element method is utilized to discretize the pile group into single pile and pile elements, and the global stiffness matrix equation of the pile group can be obtained by assembling pile

The interaction estimation of piles bored in sand/Centriškai apkrautų gręžtinių polų sąveikos vertinimas

Journal of Civil Engineering and Management, 2001
Usually a pile foundation consists of a pile group. The difference between the behaviour of a single pile and pile group is described by H. Poulos [5] using the coefficient of interaction, which indicates the pile influence on the increasing neighbouring

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

FEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

pH‐mediated activation of the lysosomal arginine sensor SLC38A9

FEBS Letters, EarlyView.
Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

Modeling the lateral response of pile groups in cohesionless and cohesive soils

International Journal of Geo-Engineering, 2018
A three-dimensional finite element approach was used to assess the lateral pile and pile group response subjected to pure lateral load. The study evaluated three pile group configurations (i.e. 2 × 1, 2 × 2 and 3 × 2 pile groups) with four values of pile

Performance of X-Section Concrete Pile Group in Coral Sand Under Vertical Loading

China Ocean engineering, 2020
To reveal the bearing capacity of the X-section pile group in coral sand, a series of model load tests are conducted. The testing results are presented as load-settlement curves, pile-soil stress ratios, distributions of side friction and axial force ...

Septin 9 PB domains coordinate centrosome positioning and microtubule acetylation to control epithelial polarity

FEBS Letters, EarlyView.
Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...
