Cracking sounds emitted from human synovial joints have been attributed historically to the sudden collapse of a cavitation bubble formed as articular surfaces are separated.Unfortunately, bubble collapse as the source of joint cracking is inconsistent with many physical phenomena that define the joint cracking phenomenon.Here we present direct evi
Lung cancer (LC) stands as the foremost cause of cancer-related fatality rates worldwide.Early diagnosis significantly enhances patient survival rate.Nowadays, low-dose computed tomography (LDCT) is widely employed on the chest as a Outdoor tool for large-scale lung cancer screening.Nonetheless, a large amount of chest radiographs creates an onerou
Here, the authors analyse a two-step constant false alarm rate (CFAR) detection problem in distributed sensor system (e.g.statistical multiple-input multiple-output (MIMO) radar) for fast-fluctuating targets (TS-AMF-II).The scheme arises when a data rate restriction forces each of the distributed systems to censor their detection statistics before
Calcium and magnesium are major nutrient elements of plants, and both play Outdoor an important role in plant growth and development.Pinus massoniana and P.hwangshanensis are important afforestation tree species in barren mountains in China.However, observation and research on calcium and magnesium nutrition of dominant forest species in China are
