where Ls(t) is the softmax loss function; Lc(t) is the central loss function; µ is the loss trade-off factor for balancing the central loss and softmax loss functions, µ∈(0, 1); w(t) is the weight parameter of the model; N is the total number of samples; k is the numb...
The Cytophone for malaria prototype (Figs. 1 and 2) was built using a near-infrared (NIR) laser (Wedge HB, Bright Solutions, Caru Carpignano, Italy) with the following parameters: wavelength,1064 nm; pulse width, 1.5 ns; pulse repetition rate, 1–2 kHz; and pulse energy on the...
The radiation equivalent dose energy spectrum ETOTof the non-visible particle detection device can be given as: ETOT=[CedGF×SR×tc×(εIR×ITOT)]∑i=1kimi,(9) wherein keis the number of the count ranges and is between 0 and (255×εIR) (unit=cps or cpm). ...

Therefore, even though the number of families in the two experimental areas is basically close, the total population of Century Color City is much larger than that of Waterside Star City. This proves that the number of residents identified through mobile phone data is reasonable and credible. ...
For this purpose, our work currently considers two different definitions to detect PoIs. Definition 1. A PoI is defined by its edge betweenness, i.e., it is defined based on the number of individual trajectories crossing a specific point or within a specific radius. A PoI in this context ...
