A bstract We show that the strong CP problem is solved in a large class of compactifications string theory. The Peccei-Quinn mechanism solves if CP-breaking effects ultraviolet completion gravity and QCD are small compared to CP-preserving axion potential generated by low-energy instantons. characterize both classes effects. To understand quantum gravitational effects, we consider an ensemble f...

results the results reveal that pq can decrease mitochondrial viability, deplete gsh content, increase mitochondrial ros formation, and enhance lpo and mitochondrial membrane damage. the pretreatment of mitochondria with ng has the ability to reduce the toxic effects of pq in isolated mitochondria. background paraquat (pq) is a dipyridyl herbicide that sustains damage due to redox cycling. an i...

The explicit semiclassical treatment of logarithmic perturbation theory for the nonrelativistic bound states problem is developed. Based upon ¯ h-expansions and suitable quantization conditions a new procedure for deriving perturbation expansions for the one-dimensional anharmonic oscillator is offered. Avoiding disadvantages of the standard approach, new handy recursion formulae with the same ...

We study the ultraviolet asymptotics in aane Toda theories. These models are considered as perturbed non-aane Toda theories. We calculate the reeection amplitudes, which relate diierent exponential elds with the same quantum numbers. Using these amplitudes we derive the quantization condition for the vacuum wave function, describing zero-mode dynamics, and calculate the UV asymptotics of the ee...

We study the ultraviolet asymptotics in affine Toda theories. These models are considered as perturbed non-affine Toda theories. We calculate the reflection amplitudes, which relate different exponential fields with the same quantum numbers. Using these amplitudes we derive the quantization condition for the vacuum wave function, describing zero-mode dynamics, and calculate the UV asymptotics o...

 Background: Paraquat (PQ), as the most widely used herbicide in agriculture, induces poisoning in humans and animals mainly through oxidative stress. This study aimed to investigate the protective effects of nano-curcumin compared with curcumin against PQ-induced mitochondrial dysfunction. Materials and Methods: Thirty-six Wistar rats were used in this study. They were separated into 6 groups...

Edaravone, an antioxidant and radical scavenger, showed protective effects against oxidative stress-like condition. Paraquat (PQ) is a toxic herbicide considerable evidence suggests that oxidative stress and mitochondrial dysfunction contribute to PQ toxicity. In this study, protective effect of edaravone against PQ induced toxicity and reactive oxygen species (ROS) generation in A549 cells and...

Paraquat (PQ), is one of the most widely used herbicides all over the world. PQ could induce dopaminergic cell death. Since dopamine involves in memory processing, we investigated the recovery effect of vitamin C on spatial memory along with oxidative stress parameters during PQ induced neurotoxicity in male rats. Rats were divided into five groups (n= 7): control (saline 0.9%), PQ (2.67 and 5 ...

Efficient Nearest Neighbor (NN) search in high-dimensional spaces is a foundation of many multimedia retrieval systems. A common approach to rely on Product Quantization, which allows the storage large vector databases memory and efficient distance computations. Yet, implementations nearest neighbor with Quantization have their performance limited by accesses they perform. Following this observ...
