The most common type of error is experimental error. In this context, error does not refer to human mistakes, such as miscalculations or using the wrong chemical. The definition of experimental error is any variance between a measurement taken during an experiment and the established value. Cons...

Since the discovery of neutrons in 1932 [1], neutron sources have emerged as an important diagnostic tool, analyzing the conditions of matter and providing insights that have revolutionized various fields of research from fundamental nuclear physics [2] to applications in medicine [3]. In their at...
In consequence, there is still much to be learned about the sources of particulate matter that may control the oxidative potential concentration7. Here we use field observations and air-quality modelling to quantify the major primary and secondary sources of particulate matter and of oxidative ...
In the present study, the air quality of a typical family house in the county of Worcestershire, UK has been studied. Three LCS measuring particle number concentrations were deployed for a period of about 50 days in different rooms within the house, as well as an additional sensor measuring ...

In theory, quantum key distribution (QKD) allows secure communications between two parties based on physical laws. However, most of the security proofs of QKD today make unrealistic assumptions and neglect many relevant device imperfections. As a result, they cannot guarantee the security of the pra...
Wildfires are increasingly frequent in the Western US and impose a number of costs including from the instantaneous release of carbon when vegetation burns. Carbon released into the atmosphere aggravates climate change while carbon stored in vegetation helps to mitigate climate change. The need for cli...

Indoor air pollution has been recognized as a key public health concern in recently years (Pope et al.,2002; Zhao et al.,2022). On the one hand, people spend more than about 75% of their time indoors. On the other hand, there are lots of emission sources for hazardous compounds in ...
