Extremely Overlapping Vehicle Counting

The challenging problem that we explore in this paper is to precisely estimate the number of vehicles in an image of a traffic congestion situation. We start introducing TRANCOS, a novel database for extremely overlapping vehicle counting. It provides more than 1200 images where the number of vehicles and their locations have been annotated. We establish a clear experimental setup which will le...

Retinoblastoma and low level radiation.

The village of Seascale, near the Sellafield nuclear reprocessing plant, is best known in epidemiological circles for its longstanding high incidence ofmalignant disease in young people,' which has recently been confirmed as having persisted during 1984-90.2 Throughout, the excess has been largely accounted for by leukaemia and non-Hodgkin's lymphoma. No cases of retinoblastoma have been found ...

Extremely Low Frequency Magnetic Field Modulates the Level of Neurotransmitters

This study was aimed to observe that extremely low frequency magnetic field (ELF-MF) may be relevant to changes of major neurotransmitters in rat brain. After the exposure to ELF-MF (60 Hz, 2.0 mT) for 2 or 5 days, we measured the levels of biogenic amines and their metabolites, amino acid neurotransmitters and nitric oxide (NO) in the cortex, striatum, thalamus, cerebellum and hippocampus. The...

Evidence for beneficial low level radiation effects and radiation hormesis.

Low doses in the mGy range cause a dual effect on cellular DNA. One is a relatively low probability of DNA damage per energy deposition event and increases in proportion to the dose. At background exposures this damage to DNA is orders of magnitude lower than that from endogenous sources, such as reactive oxygen species. The other effect at comparable doses is adaptive protection against DNA da...

Radiation Hormesis in Humans Exposed to Low Level Ionizing Radiation

Through various researches and investigations it has been established that high doses of ionizing radiation are harmful to health. There is substantial controversy regarding the effects of low doses of ionizing radiation despite the large amount of work carried out (both laboratory and epidemiological). According to the linear no-threshold (LNT) hypothesis, any amount, however small, of radiati...
