Financial Regulation and the Speed of Financial Risks

open access: yesŒconomia, 2017
This paper argues that the speed of financial risks, rather than the speed of regulators, is the key cause of financial crises. Our argument contradicts a common claim in the literature that financial crises arise because regulators cannot keep up with ...

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

open access: yesFEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

SUSTAINABILITY ASSESSMENT OF SPEED REGULATION OF URBAN TRAFFIC

open access: yesIATSS Research, 2002
Speed regulation of motor vehicles has widely affected the living environment and standard of residents in urban areas. It is believed that lower speed of motor vehicles could decrease the traffic accident rate on roads.

PARK(ing) time–How park deficiency affects the biological clock in a Drosophila model of Parkinson's disease

open access: yesFEBS Letters, EarlyView.
Drosophila park mutants serve as a model for Parkinson's disease. We used this strain to investigate the connection between oxidative stress and the circadian clock mechanism. We showed that increased oxidative stress affects the physiology of pacemaker cells, disrupting their daily structural plasticity. Lack of rhythmic signaling from pacemaker cells

Design of Control Strategies for Speed Regulation of Magnetic Reciprocating Engine

open access: yesEng
Magnetic reciprocating engines (MREs) offer an emission-free alternative to internal combustion engines; however, their practical implementation requires precise speed regulation, a challenge compounded by coupled electromechanical dynamics and inductive

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

open access: yesFEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

Power-speed coupling response characteristics of variable speed pumped storage unit under pumping mode

open access: yesInternational Journal of Electrical Power & Energy Systems
Variable speed pumped storage unit (VSPSU) has the advantage of adjustable power under pumping mode, which can better meet the regulation demand of power grid.

α‐Synuclein aggregation landscape from phase separation to neurotoxic intermediates

open access: yesFEBS Letters, EarlyView.
Alpha‐synuclein aggregation in Parkinson's disease involves a complex landscape of transient intermediates, including oligomers, fibrils and liquid–liquid phase separation (LLPS). A view is emerging in which LLPS maturation into solid‐like condensates may contribute to the formation of neurotoxic species.

Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

open access: yesFEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.
