The author studies models of a frictionless security market where the prices are continuous processes of bounded \(p\)-variation, \(p\in [1,2)\). Specifically, ``volatility terms'' of the price processes are fractional Brownian motions with index \(1 ...

The Arabidopsis mutants hls1 hlh1 and amp1 lamp1 exhibit pleiotropic developmental phenotypes. Although the functions of the causative genes remain unclear, they act in the same genetic pathway and are thought to generate non‐cell‐autonomous signals.

Microbial exopolysaccharide production by polyextremophiles in the adaptation to multiple extremes
Polyextremophiles are microorganisms that endure multiple extreme conditions by various adaptation strategies that also include the production of exopolysaccharides (EPSs). This review provides an integrated perspective on EPS biosynthesis, function, and regulation in these organisms, emphasizing their critical role in survival and highlighting their ...

Nicotinamide (NIC) and nicotinic acid (NIA) are proposed as stress signaling compounds in plants. Oxidative stress may lead to single strand breaks (SSB) in DNA, which activate poly(ADP‐ribose) polymerase (PARP). NIC and NIA are then formed from NAD. NIC and NIA can promote epigenetic changes leading to the expression of defense genes specific for the ...

Evaluation of a new method for quantification of heat tolerance in different wheat cultivars
Heat stress seriously affects wheat production in many regions of the world. At present, heat tolerance research remains one of the least understood fields in wheat genetics and breeding and there is a lack of effective methods to quantify heat stress ...

Effect of salinity on Arabidopsis thaliana seed germination and acid phosphatase activity [PDF]
The salt tolerance of four accessions of Arabidopsis thaliana (COL (Columbia), NOK2, N1438 and N1380) was evaluated during germination by the capacity of seeds to germinate in the presence of 50 mM NaCl and to maintain adequate acid phosphatase ...

Imeglimin attenuates liver fibrosis by inhibiting vesicular ATP release from hepatic stellate cells
Imeglimin, at clinically relevant concentrations, inhibits vesicular ATP accumulation and release from hepatic stellate cells, thereby attenuating purinergic signaling and reducing fibrogenic activation. This mechanism reveals a newly identified antifibrotic action of imeglimin beyond glycemic control.

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

Salt leaching of heavy coastal saline silty soil by controlling the soil matric potential
Techniques of drip irrigation are broadly applied for the reclamation of saline-alkali lands, during which effective management of water use to accelerate salt leaching is essential for crop production. In 2017, a field experiment with five treatments of
