Face stability of shield-driven tunnels using multi-tangent technique

open access: yesYantu gongcheng xuebao
To address the face stability problem of deep-buried tunnels under nonlinear conditions, using Power-Law (P-L) criterion the approximate piecewise and by multi-tangent technique, a novel multi-cone failure mechanism is developed for tunnel faces based on

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

open access: yesFEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Tau acetylation at K331 has limited impact on tau pathology in vivo

open access: yesFEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

The speed of limit order execution in the Spanish stock exchange [PDF]

open access: yes, 2005
The objective of this work is to study empirically the factors influencing the execution time in the Spanish Stock Exchange. Our dataset includes the orders and transactions of the assets belonging to IBEX 35 in the period between July and September 2000.

Calpain small subunit homodimerization is robust and calcium‐independent

open access: yesFEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

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

open access: yesFEBS 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.

Passive earth pressure analysis of berm-retained excavation by upper bound method

open access: yesYantu gongcheng xuebao, 2020
The passive earth pressure should be known for the design of the berm-retained excavation, but no reasonable method for calculating the passive earth pressure has been found until now. According to the characteristics of the berm-retained excavation, the

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.
