Spontaneous tumors can develop in different organs of various plant species without any pathogen infection and, as a rule, appear in plants with a certain genotype: Mutants, interspecific hybrids, etc. In particular, among the inbred lines of radish...

Suburban areas connect the city and the natural land. This kind of area is subject to high ecological sensitivity. To give full play to the ecological value of spontaneous plants, it was applied to the construction of suburban parks. We need to explo...

Amplified Spontaneous Emission is ubiquitous in systems with optical gain and is responsible for many opportunities and shortcomings. Its role in the progression from the simplest form of thermal radiation (single emitter spontaneous emission) all th...

Wetlands contain a large number of spontaneous plants, and the ecological value of such plants should not be underestimated. However, the influence of the surrounding environment on the composition of spontaneous plants in wetlands is still unclear....

Background: Spontaneous regression of tumors is a rare phenomenon in which cancer volume is reduced or, alternatively, a tumor completely disappears in the absence of any pharmacological treatment. This phenomenon has previously been described in sev...

Spontaneous rupture of kidney is a rare clinical entity. A 35-year-old female presented in emergency with left flank pain and features suggestive of haemorrhagic shock. Investigations showed rupture of kidney with perinephric haematoma. Emergency lef...

Spontaneous coronary artery dissection is a rather rare cause of chest pain. Recurrent spontaneous dissection is even more uncommon and the extant literature reports very few cases. We describe the case of a 46-year-old woman, who presented two spont...

The limit parameters of coal spontaneous combustion are important indicators for determining the risk of spontaneous combustion in coal seams. By analyzing the limit parameters of coal spontaneous combustion, the dangerous areas of coal spontaneous c...

Coal spontaneous combustion disasters are one of the most serious types of mine disasters in China at present, posing a huge threat to underground personal safety and coal production operations. In order to prevent and control coal spontaneous combus...

The flowback rate of fracturing fluid in shale reservoirs is often notably low, primarily due to the spontaneous imbibition of the water-based fracturing fluid. Despite their significance, the factors influencing spontaneous imbibition in shale reser...
