The $\pi-$Gluon Exchange Interaction Between Constituent Quarks

, 1998
The interaction mediated by irreducible pion and gluon exchange between constituent quarks is calculated and shown to have a strong tensor component, which tends to cancel the pion exchange tensor interaction between quarks.

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

FEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Organ‐specific redox imbalances in spinal muscular atrophy mice are partially rescued by SMN antisense oligonucleotides

FEBS Letters, EarlyView.
We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

Decadal Evolution of Atmospheric Sulfate and Nitrate and Its Potential Link to Energy Restructuring: A Case Study in Guangdong Province, China

Global Challenges
The global shift toward renewable energy and the wide adoption of electric vehicles (EVs) are expected to mitigate a series of global environmental concerns, while few studies have focused on their contribution to reducing PM2.5 concentrations.

A bidding data-driven method for collusion identification in centralized power market bidding

International Journal of Electrical Power & Energy Systems
With the increasing intelligence of the power grid and the deepening reform of the power market, the risk that some market participants violate trading rules and engage in bidding collusion has become increasingly prominent.

Exchange-correlation vector potentials and vorticity-dependent exchange-correlation energy densities in two-dimensional systems [PDF]

, 2003
We present a new approach how to calculate the scalar exchange-correlation potentials and the vector exchange-correlation potentials from current-carrying ground states of two-dimensional quantum dots. From these exchange-correlation potentials we derive

The planar cell polarity protein Vangl2 interacts with the PDZ‐domains of Scribble but not with a unique PDZ‐like domain in Inturned

FEBS Letters, EarlyView.
Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...

The Exchange Value Embedded In A Transport System [PDF]

, 2010
This paper shows that a well designed transport system has an embedded exchange value by serving as a market for potential exchange between consumers. Under suitable conditions, one can improve the welfare of consumers in the system simply by allowing ...

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

FEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Real exchange rate and terms of trade: Some empirical evidence in Malaysia, Singapore, and Thailand [PDF]

, 2009
This study examined the relationship between real exchange rate and terms of trade in Malaysia, Singapore, and Thailand in two cases, namely a three-variable case and a four-variable case. The results of co-integration tests showed that there is long-run
